Description

Hi,

I'm user from Peking University, my research interests include survey sampling and data integration.
Recently, our team is considering about adding refreshment sample to our longitudinal survey in next wave while keep PSUs the same as they were in Wave 1. I'm writing to inquire about some details about design weights calculation procedures for refreshment sample(IP4 for example).

I have read the user guide and technical report the website provide, but there are some questions:

1. as the post-sectors were selected in IP1 and refreshment sample units in IP4 were sampled in those IP1 post-sectors, how to calculate inclusion probabilities for post-sectors in IP4? are inclusion probabilities for those IP1 post-sectors the same for IP4 or updated by new sampling frame?

2. as IP4 addresses in refreshment sample are selected using systematic randomly amongst addresses not already selected for the IP1, how to calculate inclusion probabilities for those addresses in refreshment sample?

3. if a household member A in IP3 moved to a IP4 selected address, and A is selected into IP4 refreshment sample, how to calculate design weights for A?
