AdjustedRSquared

AdjustedRSquared
is a possible value for the RegressionReport option to Regress and DesignedRegress which represents the adjusted coefficient of determination.
  • AdjustedRSquared gives a modified version of the coefficient of determination RSquared which adjusts for the number of parameters in the model.
  • AdjustedRSquared is equal to 1-(n-1)/(n-p)(1-RSquared) where n=Length[data] and p is the number of parameters in the model.
