Definitions:

Coefficient Of Determination

A statistic that measures the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

Variation

The differences or deviations among individuals or items within a population, causing diversity in characteristics or outcomes.

Explanatory Variables

Independent variables in a model that are presumed to affect or determine a dependent variable.

MSR/MSE

Mean Square Residual/Mean Square Error, a measure used in statistics to estimate the variance of error or residual components.
