Reference: FAQ Questions

  1. I just downloaded the 2010 shape file for counties. When I open it the water bodies around Michigan are covered like land masses. How do I get the Great Lakes to appear as water?
  2. I downloaded the separate Cape Area Study Panel Waves 1-2-3 Household and Waves 1-2-3 Young Adult data and now I would like to merge them. How do I do that?
  3. What’s the difference between a PMSA and an MSA?
  4. ICPSR used to have a FastTrack service where some data were released fairly immediately – before normal ICPSR processing. I cannot seem to find this anymore.
  5. The PSID changed their sample in 1997 - reduced the number of original families that are included in the survey. How does this affect the weights?
  6. I want to compare the mobility of siblings in the PSID. How can I find siblings considering they no longer live in their family of origin?
  7. How do I read SAS export files?
  8. I am doing an analysis with the PSID and I need a very simple variable – race. Where is the race variable?
  9. Has anyone gotten clearance for the American's Changing Lives study, currently PI'd by Michigan researchers Jim House and Paula Lantz? We use the data because it's in-house, but if I wanted to put it in an R03 for October, would I need to go through IRB for approval?
  10. I’m interested in putting in two small grant proposals over the next few weeks – and both will be completely secondary data analysis – one of the data sets (MIDUS) is available through ICPSR and the other is the Wisconsin Longitudinal Study, which is publicly available. What is the UM policy on public use data and IRBs?
  11. How does one handle weights in a longitudinal analysis with differential sample attrition over time, etc? I am using selected years in the NLSY.
  12. The PSID is not based on a simple random sample. What variables should I use for complex sample survey variance estimation?
