Definitions:

Multicollinearity

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

Standard Errors

Measures that provide an estimation of the sampling variation, usually referring to the standard deviation of the sample mean's distribution or other parameter estimates.

Slope Coefficients

In linear regression, these coefficients represent the degree of change in the dependent variable for a one-unit change in an independent variable.

Predictor Variables

Variables that are used in statistical models to predict outcomes or responses of another variable.
