residuals.snqProfitEst function

Residuals of an SNQ profit function

Residuals of an SNQ profit function

Extract the residuals from the estimation of a Symmetric Normalized Quadratic (SNQ) profit function.

## S3 method for class 'snqProfitEst' residuals( object, scaled = TRUE, ... ) ## S3 method for class 'snqProfitImposeConvexity' residuals( object, scaled = TRUE, ... )

Arguments

  • object: an object of type snqProfitEst or snqProfitImposeconvexity.
  • scaled: logical. Return scaled quantities?
  • ...: currently not used.

Returns

residuals.snqProfitEst and residuals.snqProfitEst return a dataframe that contains the residuals for each netput and the profit.
