Coefficient of Determination Corrected

The coefficient of determination, corrected for the number of terms in the regression equation. It is typically lower and more stable than R-squared when the number of regression terms is varied.

 R²_Corrected= 1 - c ( 1 - R2 )

c = ( n - 1 ) / ( n - p - 1 )

n = number of runs; p = number of parameters estimated by regression
