Polynomial to nominal?
hi,
in the Logistic Regression, Sonar dataset has nominal data type as label... however when I import data from excel, I cannot choose data type nominal... however, logistic regression does not allow polynomial dataset as its not supported.. so what to choose then?
I find that really confusing.. in RM 5, you could choose nominal data type, is this only available in commercial releases or what happened?
is there a workaround for that?

ok thanks, I will do that, however, there seems to be a difference between polynomial and nominal, when I am using nominal dataset to train my SVM model, and later testing a polynomial test dataset on it (which should be nominal and therefore, no difference), the Apply Performance operator gives a warning that my data should also be nominal instead of polynomial...
No, the functionality was not taken away in the free editions.
You can still change the data type in the import wizard by clicking on the header, or you can manually set it in the Read Excel operator.
