[SOLVED] Binominal to Numerical

cliftonarms

I need to use a classification prediction result value that is a binominal in a calculation, but it does not function in calculations and I cannot find a "Binominal to Numerical" operator.

Im trying to do the following

prediction(binominal) x attribute(real)

The prediction variable is 1 or -1

I have tried "generate attribute" with an "if" statement to convert the binominal, but that does not work either.

Any ideas.

After half a bottle of red I had inspiration.

By treating the binomial value as a string i.e. enclosing it in quotes, you can then test its value correctly and create a real variable via "generate attribute"

Hello,

You could probably use polynominal to numerical - binominals are just frustrated polynominals after all.
