Dear members,
I am implementing the -pca- command to generate an index of socioeconomic status.� Stata will not provide values for any observation that is missing in any variable when you use the -predict, score- after the -pca- command.
I decided to use the -impute- command to fill in the missing values of the index.� Noting particularly that the missing values are not much and could be assumed to be random.
My problem is that I need a valid reference to backup the process or to see if there is a more neater way to get around this.
Any suggestion will be appreciated.
Regards
Jon
