How To... Perform Simple Linear Regression by Hand
Learn how to make predictions using Simple Linear Regression. To do this you need to use the Linear Regression Function (y = a + bx) where "y" is the dependent variable, "a" is the y intercept, "b" is the slope of the regression line, and "x" is the independent variable. This video also shows you how to determine the slope (b) of the regression line, and the y intercept (a). In order to determine the slope of a line you will need to first determine the Pearson Correlation Coefficient - this is described in a separate video (https://www.youtube.com/watch?v=2SCg8Kuh0tE).

Normality test using SPSS: How to check whether data are normally distributed
If data need to be approximately normally distributed, this tutorial shows how to use SPSS to verify this. On a side note: my new project: http://howtowritecitations.com. Statistical analyses often have dependent variables and independent variables and many parametric statistical methods require that the dependent variable is approximately normally distributed for each category of the independent variable. Let us assume that we have a dependent variable, exam scores, and an independent variable, gender. In short, we must investigate the following numerical and visual outputs (and the tutorial shows how to do just that): -The Skewness & kurtosis z-values, which should be somewhere in the span -1.96 to +1.96; -The Shapiro-Wilk p-value, which should be above 0.05; -The Histograms, Normal Q-Q plots and Box plots, which should visually indicate that our data are approximately normally distributed. Remember that your data do not have to be perfectly normally distributed. The main thing is that they are approximately normally distributed, and that you check each category of the independent variable. (In our example, both male and female data.) Step 1. In the menu of SPSS, click on Analyze, select Descriptive Statistics and Explore. Step 2. Set exam scores as the dependent variable, and gender as the independent variable. Step 3. Click on Plots, select "Histogram" (you do not need "Stem-and-leaf") and select "Normality plots with tests" and click on Continue, then OK. Step 4. Start with skewness and kurtosis. The skewness and kurtosis measures should be as close to zero as possible, in SPSS. In reality, however, data are often skewed and kurtotic. A small departure from zero is therefore no problem, as long as the measures are not too large compare to their standard errors. As a consequence, you must divide the measure by its standard error, and you need to do this by hand, using a calculator. This will give you the z-value, which, as I said, should be somewhere within -1.96 to +1.96. Let us start with the males in our example. To calculate the skewness z-value, divide the skewness measure by its standard error. All z-values in the tutorial video are within ±1.96. We can conclude that the exam score data are a little skewed and kurtotic, for both males and females, but they do not differ significantly from normality. Step 5. Check the Shapiro-Wilk test statistic. The null hypothesis for this test of normality is that the data are normally distributed. The null hypothesis is rejected if the p-value is below 0.05. In SPSS output, the p-value is labeled "Sig". In our example, the p-values for males and females are above 0.05, so we keep the null hypothesis. The Shapiro-Wilk test thus indicates that our example data are approximately normally distributed. Step 6. Next, let us look at the graphical figures, for both male and female data. Inspect the histograms visually. They should have the approximate shape of a normal curve. Then, look at the normal Q-Q plot. The dots should be approximately distributed along the line. This indicates that the data are approximately normally distributed. Skip the Detrended Q-Q plots. You do not need them. Finally, look at the box plots. They should be approximately symmetrical. The video contains references to books and articles. About writing out the results: I would put it under the sub-heading "Sample characteristics", and the video contains examples of how I would write. In this tutorial, I show you how to check if a dependent variable is approximately normally distributed for each category of an independent variable. I am assuming that you, eventually, want to use a certain parametric statistical methods to explore and investigate your data. If it turns out that your dependent variable is not approximately normally distributed for each category of the independent variable, it is no problem. In such case, you will have to use non-parametric methods, because they make no assumptions about the distributions. Good luck with your research.

Gradient Boost is one of the most popular Machine Learning algorithms in use. And get this, it's not that complicated! This video is the first part in a series that walks through it one step at a time. This video focuses on the main ideas behind using Gradient Boost to predict a continuous value, like someone's weight. We call this, "using Gradient Boost for Regression". In the next video, we'll work through the math to prove that Gradient Boost for Regression really is this simple. In part 3, we'll walk though how Gradient Boost classifies samples into two different categories, and in part 4, we'll go through the math again, this time focusing on classification.

Getting started in scikit-learn with the famous iris dataset
Now that we've set up Python for machine learning, let's get started by loading an example dataset into scikit-learn! We'll explore the famous "iris" dataset, learn some important machine learning terminology, and discuss the four key requirements for working with data in scikit-learn.

Outputting Stata Summary and Regression Tables for Excel, Word, or LaTeX
Don't you dare spend hours copying over every cell of your table by hand! There are many easier ways to get your results out of Stata. Goes over outreg2, mkcorr, and copying tables. For some reason the sound didn't kick in at the start and I had to cut out the part where I explain that you might need to download outreg2 using ssc install outreg2.

Logistic Regression Using Excel
Predict who survives the Titanic disaster using Excel. Logistic regression allows us to predict a categorical outcome using categorical and numeric data. For example, we might want to decide which college alumni will agree to make a donation based on their age, gender, graduation date, and prior history of donating. Or we might want to predict whether or not a loan will default based on credit score, purpose of the loan, geographic location, marital status, and income. Logistic regression will allow us to use the information we have to predict the likelihood of the event we're interested in. Linear Regression helps us answer the question, "What value should we expect?" while logistic regression tells us "How likely is it?" Given a set of inputs, a logistic regression equation will return a value between 0 and 1, representing the probability that the event will occur. Based on that probability, we might then choose to either take or not take a particular action. For example, we might decide that if the likelihood that an alumni will donate is below 5%, then we're not going to ask them for a donation. Or if the probability of default on a loan is above 20%, then we might refuse to issue a loan or offer it at a higher interest rate. How we choose the cutoff depends on a cost-benefit analysis. For example, even if there is only a 10% chance of an alumni donating, but the call only takes two minutes and the average donation is 100 dollars, it is probably worthwhile to call.

Compare Two Excel Lists to Spot the Differences
Over time you will collect many lists of Excel data. It can be a challenge to compare the contents of one list with the contents in another list. For example, to find out which customers do not exist in another list. In this lesson I demonstrate three techniques that you can use to compare Customer lists: 1) The =MATCH() Function 2) The VLookup() Function 3) Pivot Tables I invite you to visit my website - www.thecompanyrocks.com - to view all of my video lessons.

R Stats: Data Prep and Imputation of Missing Values
This video demonstrates how to prepare data for use with the Naive Bayes classifier and its cross-validation. It focuses primarily on the selection of suitable variables from a large data set and imputation of missing values. The video also explains the use of Spearman rank correlation for ordinal variables, where the traditional Pearson correlation is not applicable. The lesson is quite informal and avoids more complex statistical concepts. The data for this lesson can be obtained from the UCI Machine Learning Repository: * https://archive.ics.uci.edu/ml/datasets/wiki4he The R source code for this video can be found (some small discrepancies are possible): * http://visanalytics.org/youtube-rsrc/r-stats/Demo-B3-Imputing-Missing-Values.r Videos in data analytics and data visualization by Jacob Cybulski, visanalytics.org.

Machine learning is a field of computer science that uses statistical techniques to give computer systems the ability to "learn" (e.g., progressively improve performance on a specific task) with data, without being explicitly programmed. Machine learning is closely related to (and often overlaps with) computational statistics, which also focuses on prediction-making through the use of computers. It has strong ties to mathematical optimization, which delivers methods, theory and application domains to the field. Machine learning is sometimes conflated with data mining, where the latter subfield focuses more on exploratory data analysis and is known as unsupervised learning.

03 SPSS for Beginners - Descriptive Statistics
How to Use SPSS In this third video about SPSS for Beginners, Dr. Daniel shows you three ways to approach descriptive statistics in SPSS. If you want quick and basic descriptives, use the Descriptives command to get the most commonly used statistics. The Frequencies command gives you a wide range of possibilities with the most flexibility to choose exactly what output that you want. When you want maximum output with lots of graphs – or if you want to split the descriptive statistics by a categorical variable (like gender), then use the Explore command.

The submission process from the publisher's point of view
Jonathan Patience, Senior Editor at Taylor & Francis, outlines the pathway to publication; encompassing the initial decision, peer review, revision and acceptance. Recorded 13 June 2018 at a MedComms Networking event in Oxford. Produced by NetworkPharma.tv = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = ABSTRACT: Taylor & Francis Group, an Informa business, publishes more than 2,500 journals and over 5,000 new books each year, offering a range of commercial services, including accelerated publishing, supplements, sponsored focus and reprints. The company recently acquired Dove Medical Press, which specialises in the publication of open access journals across the broad spectrum of science, technology and especially medicine. This talk aims to de-mystify the process of manuscript submission to medical journals. From a publisher’s perspective, it covers considerations prior to submission, pre-submission inquiries, the stages your manuscript undergoes after submission, and how to improve your chances of manuscript acceptance. Prior to submission, it is important to check the journal’s author guidelines and aims and scope. The manuscript should be on scope for the journal, have a clear objective explaining what it adds to the literature, and include all requested sections and funding information. At peer review, the most common criticisms we receive for industry-funded papers are that they have a marketing tone, so it is important to be careful of the language used, letting data speak for itself. Other common criticisms include missing references, flawed statistical analysis, lack of transparency or results being over or under-emphasised, and missing p-values in support of claims of significance. To speed up the decision and avoid rejection post-peer review, make sure to provide clear, point-by-point responses to all reviewers’ comments, or rationale where you feel no change is needed. Adding new data, long delays during revision, unclear responses and unaddressed comments can all delay the editorial decision.

NIPS 2013 Tutorial - Causes and Counterfactuals: Concepts, Principles and Tools
Judea Pearl and Elias Bareinboim Slides: http://www.cs.ucla.edu/~eb/nips-dec2013-pearl-bareinboim-tutorial-full.pdf The traditional aim of machine learning methods is to infer meaningful features of an underlying probability distribution from samples drawn of that distribution. With the help of such features, one can infer associations of interest and predict or classify yet unobserved samples. Causal analysis goes one step further; it aims at inferring features of the data-generating process, that is, of the invariant strategy by which Nature assigns values to the variables in the distribution. Process features enable us to predict, not merely relationships governed by the underlying distribution, but also how that distribution would CHANGE when conditions are altered, say, by deliberate interventions or by spontaneous transformations. We will review concepts, principles, and mathematical tools that were found useful in reasoning about causal and counterfactual relations, and will demonstrate their applications in several data-intensive sciences. These include questions of confounding control, policy analysis, misspecification tests, mediation, heterogeneity, selection bias, missing data, and the integration of findings from diverse studies. The following topics will be emphasized: 1. The 3-layer causal hierarchy: association, intervention and counterfactuals. http://ftp.cs.ucla.edu/pub/stat_ser/r350.pdf 2. What mathematics can tell us about "transfer learning" or "generalizing across domains" http://ftp.cs.ucla.edu/pub/stat_ser/r372.pdf http://ftp.cs.ucla.edu/pub/stat_ser/r387.pdf 3. What causal analysis tells us about recovery from selection bias and missing data. http://ftp.cs.ucla.edu/pub/stat_ser/r381.pdf http://ftp.cs.ucla.edu/pub/stat_ser/r410.pdf 4. The Mediation Formula, and what it tells us about "How nature works" http://ftp.cs.ucla.edu/pub/stat_ser/r379.pdf
