question about tensorreg RMSE

Hi Prof. Zhou,

I have a question on the function kruskal_sparsereg. When I read your paper  Tucker Tensor Regression and Neuroimaging Analysis
I want to Run through your code. Every thing is fine but I can't find RSME which is in your artical from Matlab result. I seek from the glmstats1 from the result,but still I don't know which is the RSEM.
I hope you can help me.

Many thanks!
