CCHS (2007) Synthetic Files

Question

I am preparing the CCHS(2007) Synthetic files for a research team, and have found that there are missing data for WTS_S, the 'shared' Weight variable.  This is unexpected, as all the cases have a weight for the Master weight variable, WTS-M.

The research team would appreciate elucidation on this point!

Answer

My contact in Health Statistics Division provided the following explanation for the missing WTS_S data in the CCHS 2007 synthetic file:

"The reason for WTS_S being blank is because it's the share weight and therefore only populated by users that agreed to share their data."

  1. Is WTS_M the only weight variable for cycle 4.1? Do you use it for both descriptive and regression analyses?
