MeanCenterNumCellRows


Unit:SDL_datatable
Class:TDataTable
Declaration:procedure MeanCenterNumCellRows (Means: TVector);

The method MeanCenterNumCellRows transforms the rows of the numeric cells (cells which are neither marked as csNAN, nor as csUndefined) of the data table in a way that each row of the matrix has thereafter a zero mean. The original mean of all rows are returned in the parameter Means. The matrix must not contain nominal or ordinal variables, otherwise an exception will be raised. MeanCenterNumCellRows triggers the OnChange event.

Please note that size of the vector parameter Means has to be equal to NrOfRows. Means may be set to NIL, if these results are not needed.
