[SOLVED] Binominal to Numerical
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.

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

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"
