Definitions:

Independent Variables

Independent variables are variables in a study or experiment that are manipulated or categorized to observe their effect on dependent variables, without being affected by other variables in the study.

Collinearity

Collinearity is a condition in statistical modeling where two or more predictor variables are closely linearly related, potentially affecting the model's estimates and interpretations.

F-test

A statistical test used to compare the variances of two populations to assess the equality of their means.

Multicollinearity

A statistical phenomenon in which multiple independent variables in a regression model are highly correlated, potentially undermining the statistical validity of the model.
