Dear statalisters,

I have a population of company's. I want a sample from this population,
but the probability of a company to be sampled has to be equivalent with
the number of employees (let's call this "size").

So I thought i could
-sample 10 [fweight=size]

To get a 10 percent sample. But -sample- doesn't accept weights. A
solution might be to expand the dataset with size, but then a company
can get sampled several times if it has more than one employee, and I
don't want that to happen. I think there must be a very simple solution,
but I haven't been able to find it.

Any help would be much appreciated.

Willard
