A statistical measure represented by R^2 that explains the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

SSE

Sum of Squared Errors, a measure used in statistical models to quantify the variance between observed and predicted values by summing the squared differences.

Error Variable

A variable in statistical or mathematical modeling that represents the difference between an observed value and the value predicted by a model.

Mean
