Hi,

I am using principal components to make an index
comprising 8 different variables (I am basically using
the first principal component as my index). 
I have a two-part question. 

1. How do I obtain the weights assigned to each
variable? 

2. How do I obtain the standard errors of the
predicted values after using -factor, pcf- ?

Best regards,
