Definitions:

Estimated Partial-regression Coefficient

A measure used in multiple regression analysis that represents the relationship between a designated independent variable and the dependent variable, with other variables held constant.

Adjusted Multiple Coefficient of Determination

A statistical measure that adjusts the coefficient of determination (R-squared) for the number of predictors in a multiple regression model, providing a more accurate assessment of the model's explanatory power.

Multiple Standard Error

The standard error calculated for multiple measurements or estimates, which quantifies the variability or precision of those measurements.

SSR

Stands for Sum of Squares due to Regression, which quantifies the variation explained by the regression model, comparing the estimated values to the mean of the dependent variable.
