V-fold Cross Validation
-
Hello,
I would like to know how can I do V-fold Cross Validation using GeneXproTools. Anything can be done ?
-
Hi,You can indeed do v-fold cross-validation quite easily in GeneXproTools. I describe how this can be done for Regression, Classification and Logistic Regression in the Knowledge Base. Follow any of the links below for a detailed description:Candida Ferreira

Ok I would like to do 10-fold cross validation. Is it correct ? I have imported best fittness model 10 times.
-
Yes, that’s correct. For the sub-sampling in the Settings Panel you can also choose Random for the Validation Set, but Shuffled also works in this case as you set a total of 75 records for validation and chose a sub-sample of 35. But you could have used the entire validation set (the 75 records) and Random sub-sampling.Candida Ferreira

I have a one question. What have I do when i would like to do 30% and 40% cross validation. How many times should I copy my model ?
-
We've automated this whole process with GeneXproTools 5.0 MR2! See the blog post on Bootstrap Cross-Validation for details.
Howdy, Stranger!
