Definitions:

Slope Coefficients

In linear regression, the numerical values that multiply the predictor variables, representing the change in the response variable for a one-unit change in the predictor.

Multicollinearity

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

Independent Variables

Factors in a study or simulation that are deliberately changed to observe their impact on outcome variables.

Dependent Variable

The variable in an experiment or study that is expected to change in response to manipulations of the independent variable.
