get global, local and unique variance #3

Open isglobal-brge opened 7 years ago

isglobal-brge commented 7 years ago

I've been running your script and it seems that it runs without problems with my data. My question is: How can I get global, local and unique variance from the OnPLS model? (so far I'm including 3 tables but the idea is to use 7 - my main aim is to estimate the local variance between 1 table and the rest - I guess this can reduce the computing time, isn't it?)

Yes, computing only the intersection between one block and the rest should speed up the computational time significantly. In fact, this should be just the globally joint model that you configure to predict the single block from the rest.

Currently, the global, local and unique variance can not be decomposed. I will add this functionality when I get the time, but from your description, it does not seem like you need the complete decomposition.

Thanks for the answer. Maybe I did not explain very well my question or I have not understood your answer. I was wondering how to get model information from your functions - An illustrative example would be very helpful

Sorry for the late response. It's been very busy here. The estimators currently don't return or compute/store any statistics. This will be added when possible, but my time for this project is limited at the moment. (You're more than welcome to submit pull requests! ;-))

Is there any particular model information that you'd like to be able use?

Hi there,

I'd like to reopen this issue as I am trying to calculate and OnPLS model similarly to the work described in https://pubs.acs.org/doi/10.1021/acs.analchem.8b03205 in particular i would like to be able to estimate all local and unique components on top of the global ones. Which you guys appear to have code for!

Thank you in advance

Hi @tomlof, Does this one take care of? Can we get global, local, and unique variance now? And could you also explain the P, W, and T from the onpls? Can you also explain how to design the predComp ? Thanks a lot! K
