Hi,

i have found the Numerical to binominal Operator. The problem is, that this Operator is only usefull when applying to a numerical column that have 2 numerical values otherwise many information will get lost.

I am looking for an solution that do the following:

have a column with many different numerical values -> discretize to 10 bins and then -> replace this column by 10 columns which have only the values 1 or 0. 


greetings
