Definitions:

Regression Slope Coefficients

The estimates that measure the relationship between the dependent variable and each independent variable in regression analysis.

Y-intercept

The point where a line, curve, or surface intersects the y-axis of a coordinate system.

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.
