What are Dummy Variables in Regression?

Dummy variables in regression are artificial variables created to represent categorical data numerically. They take binary values (0 or 1) to indicate the presence or absence of a particular category. Since regression models require numerical input, dummy variables allow categorical variables (e.g., gender, region, or product type) to be incorporated into the analysis. ► E-BOOK https://numiqo.com/statistics-book ► Example data https://numiqo.com/statistics-calcula... ► Regression Calculator https://numiqo.com/statistics-calcula... ► Playlist: 1) What is a Regression Analysis?    • Regression Analysis: An Easy and Clear Beg...   2) What is Simple Linear Regression?    • Simple Linear Regression: An Easy and Clea...   3) What is Multiple Linear Regression?    • Multiple Linear Regression: An Easy and Cl...   4) What is Logistic Regression?    • Logistic Regression: An Easy and Clear Beg...   ► Tutorials: Regression Analysis https://numiqo.com/tutorial/regression Linear Regression https://numiqo.com/tutorial/linear-re...
