Fit Distribution to Feature Data

Group (Subgroup)

Statistics (Ensemble)


This Filter will fit "common" statistical distributions (as chosen by the user) to specific Feature level attributes. The user can chose both which attributes to fit and with what distribution to fit them. The parameters that define the "best-fit" distributions will be stored in an Ensemble array. The user also has the option to remove biased Features from the fitting process.

Note: The array selected must be a scalar array
