Definitions:

Partial Regression Slope Coefficients

Parameters in a multiple regression model that represent the individual effect of each independent variable on the dependent variable, holding all other variables constant.

Standard Error of Estimate

A statistical measure that provides an estimation of the standard deviation of the error term in a regression model, indicating the accuracy of predictions.

Coefficient of Determination

A measure in statistical models that indicates the proportion of the variance in the dependent variable predictable from the independent variables, often symbolized as \(R^2\).

Multicollinearity

A statistical phenomenon in which predictor variables in a regression model are highly correlated, potentially leading to difficulties in estimating separate effects on the dependent variable.
