Web26 de out. de 2024 · What happens when I normalize the dependent variable but not the independent variables in a linear regression ? Nothing. How will I interpret the model as opposed to normalizing both dependent and independent variables. If you normalize independent variables you will be able to compare/interpret weights of them after fitting.

Web20 de abr. de 2024 · By normalizing the variables, we can be sure that each variable contributes equally to the analysis. Two common ways to normalize (or “scale”) variables include: Min-Max Normalization: (X – min (X)) / (max (X) – min (X)) Z-Score Standardization: (X – μ) / σ. Next, we’ll show how to implement both of these techniques in R.
