Hi all, I was wondering if anyone could give me some suggestion on command -svytab-.My goal is to get the frequencies distribution of most of thevariablesin a survey data set (with sampling weight). I don't choose -tabulate-because it can't be used together with pweight. So, I generate a constant variable which equals 1 and -svytab eachvariable I'm interested with in the data set together with theconstantvariable 1. The problem is that, it takes about 5 minutes to do just one svytab . After svytab for 4 variables, stata shows there's not enough memory to do svytab to the rest variables,although the memory has already been set to 1g. (The data set has 3,932,343 observations and 90 variables.) So, my questions are as follows. (1) Is it normal that -svytab- need so much memory and it works so slowly ? (2) Is there any better way to check frequencies of a lot of variables with sampling weight?(3) Suppose the goal of checking frequencies is just to see ifthere'sanything weird or any errors in the data. Is there any problem if I just use -tabulate- and put the weight variable as aweight or fweight instead of pweight? Thanks a lot for your help!
