about the loading plot and score plot #23

Closed weiping2020 closed 2 years ago

weiping2020 commented 2 years ago

hi， could you please tell how to do the loading plot by PCA library? and what is the different between loading plot and score plot?

erdogant commented 2 years ago

The loadingplot is named the biplot. You can find more information on the documentation pages

The blog can also be interesting to read where I describe more about the interpretation of the loadings with the biplot and and the scree-plot.

thanks erdogant, I have plotted the loading plot, it has loading points and scatter points, so how to delete the scatter points( initial points) ? just show the loading arrows

See here

model.biplot(cmap=None, label=False, legend=False)

re-open the issue if it was not clear.
