Definitions:

Independent Variable

A variable in an experiment or statistical model that is manipulated or controlled by the experimenter to observe its effect on a dependent variable.

SSE

Sum of Squared Errors; a measure of the discrepancy between the data and an estimation model.

SST

Sum of Squared Total, a measure used in statistics to quantify the variance within a set of observations.

Coefficient Of Determination

The Coefficient of Determination, denoted as R², measures the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
