Principal Component Analysis

[Akanksha Aggarwal]

Hi

I have a non Stata request.
I have to use PCA to create an index for cities in my dataset using various city characteristics. Want to read about PCA. Looking for research papers which have used PCA to create indexes or general content on the topic.

Thanks.
