This Time Series Analysis (Part-2) in R tutorial will help you understand what is ARIMA model, what is correlation & auto-correlation and you will alose see a use case implementation in which we forecast sales of air-tickets using ARIMA and at the end, we will also how to validate a model using Ljung-Box text. Link to Time Series Analysis Part-1: https://www.youtube.com/watch?v=gj4L2isnOf8 You can also go through the slides here: https://goo.gl/9GGwHG A time series is a sequence of data being recorded at specific time intervals. The past values are analyzed to forecast a future which is time-dependent. Compared to other forecast algorithms, with time series we deal with a single variable which is dependent on time. So, lets deep dive into this video and understand what is time series and how to implement time series using R. Below topics are explained in this " Time Series in R Tutorial " - 1. Introduction to ARIMA model 2. Auto-correlation & partial auto-correlation 3. Use case - Forecast the sales of air-tickets using ARIMA 4.

Pandas has in built support of time series functionality that makes analyzing time series extremely efficient. In this tutorial, we will see how date_range function allows to generate datetimeindex with specific start and end dates. It can also generate periods with different frequencies such as hourly,daily,monthly, weekly etc. We will then cover how asfreq function can be used to resample dataframe to a different frequency.

Introduction to Time Series Analysis using @RISK 6 - Palisade Webcast
 
01:14:20
In this session we explore the Time Series functionality of @RISK 6. Many variables in our models such as commodity prices, indices and rates are in fact time series, requiring special models such as ARIMA, GARCH and Brownian Motion for accurate forecasting. @RISK 6 allows these to be constructed as functions on your spreadsheet, and when the parameters are unknown the models can be fitted to historical data. A goodness-of-fit test helps determine the most appropriate model. The created models are stochastic and form an integral part of any simulation run on your spreadsheet model.

Time Series - 1 Method of Least Squares - Fitting of Linear Trend - Odd number of years
 
14:40
#Statistics #Time #Series #Business #Forecasting #Linear #Trend #Values #LeastSquares #Fitting #Odd Definitions  “A time series may be defined as a sequence of values of same variable corresponding to successive points in time.” – W. Z. Hersch  “A time series may be defined as a sequence of repeated measurement of a variable made periodically through time.” – Cecil H. Mayers Analysis of Time Series “The main object of analyzing time series is to understand, interpret and evaluate changes in economic phenomena in the hope of more correctly anticipating the course of future events.” – Hersch A time series is a dynamic distribution, which reveals a good deal of variations over time. Statistical methods are, therefore, required to analyze various types of movements in a time series. There may be cyclical variations in general business activity and there may be short duration seasonal variations. There are also some accidental and random variables. The primary purpose of the analysis of time series is to discover and measure all such types of variations, which characterize a time series. Time series analysis means analyzing the historical patterns of the variable that have occurred in past as a means of predicting the future value of the variable. It helps to identify and explain the following: (i) Any regular or systematic variation in the series of data which is due to seasonality- the ‘seasonal’ (ii) Cyclical patterns. (iii) Trends in the data. (iv) Growth rates of these trends. This method can be useful when no major environmental changes are expected and it does highlight seasonal variations in sales and consumer demand. However, time series analysis is limited when organizations face volatile environments. Components of Time series – The time series are classified into four basic types of variations which are analyzed below: T = Trend S = Seasonal variations C = Cyclic variations I = Irregular fluctuations. This composite series is symbolized by the following general terms: O = T x S x C x I Where O = Original data T = Trend S = Seasonal variations C = Cyclic variations I = Irregular components. This Multiplicative model is to be used when S, C, and I are given in percentages. If, however, their true (absolute) values are known the model takes the additive form i.e., O=T+C+S+I. Algebraic Method For Finding Trend (Method of curve fitting by the principle of Least Squares) Fitting of Linear Trend Let the straight line trend between the given time series values (y) and time (x) be given by the standard equation: y = a + bx Then for any given time ‘x’ the estimated value of ye as given by the equation is ye = a + bx The following two normal equations are used for estimating 'a' and 'b'. Σy = na + bΣx Σxy = aΣx + bΣx^2 When Odd No. of Years, [X = (Year – Origin) / Interval] Case Given below are the figures of sales (in '000 units) of a certain shop. Fit a straight line by the method of least square and show the estimate for the year 2017: Year: 2010 2011 2012 2013 2014 2015 2016 Sales: 125 128 133 135 140 141 143 Time Series, Linear Trend, Method of Least Squares, Statistics, MBA, MCA, BE, CA, CS, CWA, CMA, CPA, CFA, BBA, BCom, MCom, BTech, MTech, CAIIB, FIII, Graduation, Post Graduation, BSc, MSc, BA, MA, Diploma, Production, Finance, Management, Commerce, Engineering , Grade-11, Grade- 12 - www.prashantpuaar.com

Speaker: Christopher Batey Time series data is everywhere: IoT, sensor data, financial transactions. The industry has moved to databases like Cassandra to handle the high velocity and high volume of data that is now common place. However data is pointless without being able to process it in near real time or do batch analytics. That's where Spark combined with Cassandra comes in, what was one just your storage system can be transformed into your analytics system, and you'll be surprised how easy it is! Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients. Cassandra also places a high value on performance. In 2012, University of Toronto researchers studying NoSQL systems concluded that "In terms of scalability, there is a clear winner throughout our experiments. Cassandra achieves the highest throughput for the maximum number of nodes in all experiments" although "this comes at the price of high write and read latencies Apache Spark is a fast and general engine for large-scale data processing.

ITSx comprehensively introduces analysts to interrupted time series analysis (ITS) and regression discontinuity designs (RD) from start to finish, including definition of an appropriate research question, selection and setup of data sources, statistical analysis, interpretation and presentation, and identification of potential pitfalls. At the conclusion of the course, students will have all the tools necessary to propose, conduct and correctly interpret an analysis using ITS and RD approaches. This will help them position themselves as a go-to person within their company, government department, or academic department as the technical expert on this topic. ITS and RD designs avoid many of the pitfalls associated with other techniques. As a result of their analytic strength, the use of ITS and RD approaches has been rapidly increasing over the past decade. These studies have cut across the social sciences, including: Studying the effect of traffic speed zones on mortality Quantifying the impact of incentive payments to workers on productivity Assessing whether alcohol policies reduce suicide Measuring the impact of incentive payments to physicians on quality of care Determining whether the use of HPV vaccination influences adolescent sexual behavior WHAT YOU'LL LEARN The strengths and drawbacks of ITS and RD studies Data requirements, setup, and statistical modelling Interpretation of results for non-technical audiences Production of compelling figures

Time Series analysis is the analysis of uni-variate time varying data which is used to predict future values of a certain variable. In this video, you will learn about what are time series, cross section and Panel data sets, what are univariate and multi variate time series, what is stationarity, what is a white noise process etc. You will Learn about AR, MA, ARMA and ARIMA models. You will learn about building an ARIMA model using Box-Jenkins method.
