Hi.
I'm using weights from the European social Survey which have three different weights: design, population and post estimation weights. I really don't know what kind of weights they are (if fw, or aw or pw). I simply tried to graph (histogram) a variable ( worry about climate change) using weights but stata said: "may not use noninteger frequency weights". I'm aware of that would mean that my weights are not integer and that I need frequency weight, but the question is: can i transform my non integer weights in integer ones?
i attach a brief doc that explains the ESS database's weights. (http://www.europeansocialsurvey.org/...ing_data_1.pdf)
Thank you very much
