Oreilly - Regression Analysis and Hypothesis Testing in R
by Michael Grogan | Released January 2018 | ISBN: 9781492028543
Learn from data science expert Michael Grogan in this tutorial that teaches you how to use regression analysis and R to uncover high-value business insights hidden inside large datasets. The course reviews the meaning of regression analysis; shows you how to use R to conduct regression analysis techniques on cross-sectional and time series datasets; discusses standard regression techniques such as Ordinary Least Squares (OLS) and Logistic Regressions; and surveys the various violations of OLS and how these can be corrected. By the end of the course, you'll understand the theory behind regression analysis and how to put this theory into practice. Learners should have a basic understanding of statistics, familiarity with data types (i.e., nominal, ordinal, interval, and scale), and preferably some prior experience with R.Learn to uncover key business insights hidden inside data using regression analysis and RGain hands-on experience running linear and logistic regressions using RUnderstand how to interpret statistical output and derive meaning from resultsExplore methods that screen and correct for violations of Ordinary Least Squares assumptionsMichael Grogan is a data scientist who specializes in R, Python, and Shiny.
