VIP for OPLS and O2PLS in SIMCA-Q 32-bit occasionally missing (Q872)
For OPLS and O2PLS models the different VIP-vectors are sometimes not calculated in the 32-bit version. This means that occasionally you may get empty vectors. When the vectors are calculated, the results are correct.
The vectors are: VIP (total), VIP predictive, VIP orthogonal, VIPcv, VIPcvSE and contributions weighted by VIP.
In the 64-bit version the vectors are always calculated.
If possible, run the 64-bit version.
Fixed in SIMCA-Q 14.1.1.
There is a memory handling issue in the 32-bit versions for these particular vectors.
