Read(511) Label: sequence, correct skewness,

Description:

Correct skewness of a numeric sequence.

Syntax:

A.corskew()

During modeling, correct skewness of numeric variable A, handle outliers, and return the result sequence of correction and a sequence of correction and handling process records Rec

A.corskew@r(Rec)

During scoring, correct skewness of numeric variable A according to correction process records Rec
