weighting

erdema

Hi,
I try to use 'the number of observations' column to indicate the weight of rows.
I set my column role as weight but it does nto work. In clementine it is defined in modeling node....
How do we set the role weight to set row importance?

Thanks in advance
Erdem

Hi,
you have to use the "Set Role" operator, select the column name (columns are called attributes in RM) and select the role "weight". Then you need to apply an modeling algorithm that is capable of handling weights, otherwise they will be just ignored.
