Sir, I have to create an index (weighted). Can I assign weight through PLA to different components based on their importance? Please give some steps for this

[@theoutlier7395]

Multiply the original variables by their corresponding component scores (from the PCA loadings).
Sum the weighted scores to obtain the final index.

[@priyagupta-ht2xb]

Is it ok to consider the item belongs to that component where the item itself indicates higher loading

[@theoutlier7395]

yes those items have a high loading you can consider rest please ignore
