categorical IV and q-squared results

Post by sebastianrot »

hi!!

i have a categorical IV and have finished interpreting the data. the last thing I need to do is interpret q-squared. when I run the predictive model the q-squares are all negative. but when I run them unstandardised they are well above 0.

which version (standardised/unstandardised) should i interpret?

i also thought that due to the categorical IV - q-square and predictive relevance cannot be properly measured and thats why they are showing up negative. please let me know! really would appreciate any help

Yes, if you have a binary IV the predictive results are not correct for standardized results. We have fixed the issue and it will be correct with the next release. The unstandardized results are correct.
