Hi Statalisters,
I have two (probably) independent samples taken from the same population under two different surveys conducted a few years apart. I'd like to check whether the frequencies for a particular indicator match between the samples. I don't expect these proportions to change much over time (though I can't rule it out). The indicator uses multiple categories which are mutually exclusive and not ordinal, e.g.:
What is your car's color?
Red
Green
Blue
Black
etc.
I want to check that survey A captured, basically, the same proportions of red/green/blue that survey B did. I *think* I should be using a Chi-square goodness of fit for this (csgof); except that I'm comparing two samples, rather than the sample versus the population. Anyone know what other statistical test I should be using? I'm a bit stuck, and am considering just eyeballing it: using svy: tab on both and just comparing the confidence intervals. But I feel like this is a crude way of doing things.
Thanks very much!
