Description

Hi,

I am working on the nurse health assessment data combined to the blood sample data and the full main interview. I focus only on the wave 2.
My aim is to describe the biomarkers and use them to construct a score representative of health condition according to gender and age.

My problem is about the weighting strategy. I already posted a message on the forum (#430) and now I consider the indbdub_xw weight variable.
  • Why is there people who have a weighting value of 0 ? I count 670 individuals in this case from n=9882. In addition, most of them do not have missing values on biomarkers so, why do we not use them ?
  • I have to delete individuals who have missing values (because I would use a PCA on my data). Is it still correct to use the indbdub_xw variable ?

Thank you for your response.
Gaelle
