Good morning everyone, hope you doing great !
I was wondering if it's possible to put a log2 scale model for Multivariate analysis on Simca (PCA/PLSDA/OPLSDA).
Am using the version 14.1 and for the moment i have only few options which are not always convenient for mass spectrometry data (see picture bellow)
I would appreciate if anyone could help about that.
Thank's by advance !
Hi,
in SIMCA you can actually transform your data using different functions. In the home section click on edit and then selectthe transform panel. After selecting all the variables, on the bottom of the panelyou can use different transformation functions. Moreover is possible to use the auto-transform function that helps you to select the best function.
good luck
Hello i really appreciate your help ! I tried before that transformation but it was not the same as compared in R studio. I thought maybe there is a formula that i can put manually to do that.
In mass spectrometry data, switching between data scales can change the whole interpretation of the results. For that reason i want to apply the same transformation as my team do with Rstudio..
