BS10- What are the challenges in using Regression analysis?

In this video, part 1 of chapter 6 of Linear regression sub series, we discuss the common challenges in using regression analysis and how to address them effectively. Topics include role of sample size, setting criteria for selecting variables to include in the regression equation, deciding how to code nominal & ordinal variable outcomes, whether to code outcomes like success and failure as 0 & 1 or 1 & 2 etc. We also explore what constitutes a "good enough" R-squared value in different scenarios, and discuss use of linear vs. non-linear models. This video provides practical insights to help you make informed decisions and avoid pitfalls when performing regression analysis.
