Thank you once again for your support.
In the following zip folder, I have put all the files for a short example of what I have done.
pca_analysis is the main file to run. It calls 3 input files and merge them, then I perform Principal Component Analysis for this complete database.
The results are displayed in PCA-output.txt
At the end, I open it and start to see what is the percentagem of total explained variability retaining only 2 components, because I only want to display the results in 2D plot. Then retaining the first two columns of loadings I am able to write the model equations.
A reviewer kindly suggest me that it would be very interesting to perform Sobol’s indices analysis to the dataset.
It is a completly new area of knowledge for me and through my understanting I think I have to perform global sensitivity of the indices of PC1 and PC2 for each analysis. Maybe, I am wrong. Still I was not able to do it.
I hope I could explain my issue.
