Hi,

For example in the operator CFSFeatureSetEvaluator i use this inside another operator (FeatureSelection) but with ANOVA i don't now what to do

The first part is perfectly fine - but I don't get why you would want to integrate the ANOVA operator inside this setting?

The ANOVA operator can only used to calculate if two performance vectors (which in fact could guide the feature selection process) significantly differ.

Cheers,

Ingo
