Hi,

Does anyone know how to get variables in each of PC1, PC2, PC2 in PCA?

Thank you.

Load your data set into JMP, then run the Principal Components Analysis from the main menu, i.e. Analyze | Multivariate Methods | Principal Components. You'll get an output that initially shows a scree plot, but you can expand that to show scores and loadings plots among other options by clicking on the "Principal Components / Factor Analysis" bar. At the bottom of that options list you'll find "Save Principal Components". If you click on that, you'll be asked how many components you want to save. Answering that question will append that number of principal components onto the right of your original data table: they'll be called "Prin1", "Prin2" etc - from where you can save them, import them into other analyses etc.
