Hello,

I have a longitudinal population survey data. This is actually my first time working with such a huge dataset, and I am having a really bad time in setting it up. I am describing the dataset below. I would be really grateful if anyone can point to the right direction.

It is a population survey. The strata are the districts. Primary sample units are individuals. The time period is from 1980 to 2019. The variables include both continuous and categorical variables. The categorical variables represent demographic characteristics of the sample primary sample units. What I am interested in is finding out the patterns in one of the continuous and one of the categorical variables, given the others, through time.

I have tried to setup the data with svy. Since the survey was with replacement, there is no FPC. However, this was not fruitful; most commands were still reporting repeating time values or too many values. Furthermore, I am not sure whether I should subset the dataset because I cannot figure what the variables would represent then.

I am sure that I am lacking some basics for data like this. If anyone can point to the right resource, that would be very helpful too.

Thank you.
