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.

Probability functions: pdf, CDF and inverse CDF (FRM T2-1)
[Here is my XLS @ http://trtl.bz/2AgvfRo] A function is a viable probability function if it has a valid CDF (i.e., is bounded by zero and one) which is the integral of the probability density function (pdf). The inverse CDF (aka, quantile function) returns the quantile associated with a probability, q = F^(-1)(p), whereas the CDF returns the probability associated with a quantile: p = F(q).

In this section I’m going to start to look at the statistical functions in Excel 2013. I’m not going to assume that you’re a statistician and have a deep and broad knowledge of statistics, but most people have enough exposure to statistics in everyday life nowadays to understand the kinds of terms and terminology that I’m going to use. Microsoft Excel has been used in statistics and by statisticians for quite a few years now and it’s actually a pretty strong tool. As we’ll see during this section and later on in the course, not only can we do some very useful numeric work but we can also use some of the charting and graphing features of Excel 2013 to look at statistical questions and statistical issues. There are some specialist pieces of software available to do a lot of these sort of statistical number crunching that you might need but the advantage of Excel, of course, is that it does many other things as well and many more people have copies of Microsoft Excel. So if you’ve got a particular statistical problem to solve or a piece of work to do, the chances are that Excel can help you to solve that problem or do that job for you if it can’t then you probably will need to look at one of the more specialized products. Now for the purposes of this course I’ve divided the application of the statistical functions in Excel 2013 into three groups, and those three groups are: description, prediction, and inference. The first one we’re going to look at is description and by that I mean we take some statistics, in our case, a set of numbers and we look at ways of describing that set of numbers. So we’re really just looking at fact finding. We’re saying what are the features of this set of numbers that will help us, for instance, understand what the numbers tell us or maybe even compare them with other similar or related sets of numbers? I’m then going to look at prediction and in particular at regression and how we can use some existing measurements to predict what might happen in the future. The third category in relation to using Excel 2013 in statistics is inference. By inference what we mean is the ability to infer something about a population by measuring a sample from that population. So typically we’re talking about things like doing opinion polls, maybe taking 10 or 100 or 1,000 people, getting their opinion, measuring some feature, and from that measurement inferring something about the population. Now this is an area that requires quite a bit more statistical knowledge so I’m not going to go into it in great detail but I’ll look at one or two examples of how Excel can help with inferential statistics. Now I’m looking at the list of statistical functions in Excel Help here and one of the things you’ll notice straightaway is that it is a very, very long list of function. It’s one of the areas of Excel where the most functions are available. And if you’re not a statistician, many of those won’t really mean a lot to you. I’m not going to worry too much about those very detailed statistical functions, the ones that involve quite a lot of technical knowledge. I’m going to look at the more straightforward ones in this section. But I would like to point something out. If you’ve used an earlier version of Excel and if you’ve used statistical functions before, many of those functions have been superseded in Excel 2010 and Excel 2013 with functions of a similar name but with extensions. For instance, the quartile functions that I’ll look at a little bit later QUARTILE.EXC and QUARTILE.INC, for example.

Qualitative analysis of interview data: A step-by-step guide
The content applies to qualitative data analysis in general. Do not forget to share this Youtube link with your friends. The steps are also described in writing below (Click Show more): STEP 1, reading the transcripts 1.1. Browse through all transcripts, as a whole. 1.2. Make notes about your impressions. 1.3. Read the transcripts again, one by one. 1.4. Read very carefully, line by line. STEP 2, labeling relevant pieces 2.1. Label relevant words, phrases, sentences, or sections. 2.2. Labels can be about actions, activities, concepts, differences, opinions, processes, or whatever you think is relevant. 2.3. You might decide that something is relevant to code because: *it is repeated in several places; *the interviewee explicitly states that it is important; *you have read about something similar in reports, e.g. scientific articles; *it reminds you of a theory or a concept; *or for some other reason that you think is relevant. You can use preconceived theories and concepts, be open-minded, aim for a description of things that are superficial, or aim for a conceptualization of underlying patterns. It is all up to you. It is your study and your choice of methodology. You are the interpreter and these phenomena are highlighted because you consider them important. Just make sure that you tell your reader about your methodology, under the heading Method. Be unbiased, stay close to the data, i.e. the transcripts, and do not hesitate to code plenty of phenomena. You can have lots of codes, even hundreds. STEP 3, decide which codes are the most important, and create categories by bringing several codes together 3.1. Go through all the codes created in the previous step. Read them, with a pen in your hand. 3.2. You can create new codes by combining two or more codes. 3.3. You do not have to use all the codes that you created in the previous step. 3.4. In fact, many of these initial codes can now be dropped. 3.5. Keep the codes that you think are important and group them together in the way you want. 3.6. Create categories. (You can call them themes if you want.) 3.7. The categories do not have to be of the same type. They can be about objects, processes, differences, or whatever. 3.8. Be unbiased, creative and open-minded. 3.9. Your work now, compared to the previous steps, is on a more general, abstract level. You are conceptualizing your data. STEP 4, label categories and decide which are the most relevant and how they are connected to each other 4.1. Label the categories. Here are some examples: Adaptation (Category) Updating rulebook (sub-category) Changing schedule (sub-category) New routines (sub-category) Seeking information (Category) Talking to colleagues (sub-category) Reading journals (sub-category) Attending meetings (sub-category) Problem solving (Category) Locate and fix problems fast (sub-category) Quick alarm systems (sub-category) 4.2. Describe the connections between them. 4.3. The categories and the connections are the main result of your study. It is new knowledge about the world, from the perspective of the participants in your study. STEP 5, some options 5.1. Decide if there is a hierarchy among the categories. 5.2. Decide if one category is more important than the other. 5.3. Draw a figure to summarize your results. STEP 6, write up your results 6.1. Under the heading Results, describe the categories and how they are connected. Use a neutral voice, and do not interpret your results. 6.2. Under the heading Discussion, write out your interpretations and discuss your results. Interpret the results in light of, for example: *results from similar, previous studies published in relevant scientific journals; *theories or concepts from your field; *other relevant aspects. STEP 7 Ending remark Nb: it is also OK not to divide the data into segments. Narrative analysis of interview transcripts, for example, does not rely on the fragmentation of the interview data. (Narrative analysis is not discussed in this tutorial.) Further, I have assumed that your task is to make sense of a lot of unstructured data, i.e. that you have qualitative data in the form of interview transcripts. However, remember that most of the things I have said in this tutorial are basic, and also apply to qualitative analysis in general. You can use the steps described in this tutorial to analyze: *notes from participatory observations; *documents; *web pages; *or other types of qualitative data. STEP 8 Suggested reading Alan Bryman's book: 'Social Research Methods' published by Oxford University Press. Steinar Kvale's and Svend Brinkmann's book 'InterViews: Learning the Craft of Qualitative Research Interviewing' published by SAGE. Text and video (including audio) © Kent Löfgren, Sweden
