Hi !

I have applied attached stability process but I am not sure if I correctly selected log parameters for for jaccard and kuncheva indexes. Could you please help me to correct the process and advice how can I interpret the results of kucheva and jaccard index ?

Hello, @ozgeozyazar

When I import your process, RapidMiner tells me the following:

I need more information, as you are working with an old version of RapidMiner, and you haven't provided information on what plugins are you using, etc.

All the best,

Rodrigo.
