Dear all,

I would like to know your opinion about the following issue: I need to create (starting from my original dataset) a series of 'fictious datasets' in which I simulate another scenario changing the distribution of a given characteristics, and then calculating (for each 'fictious dataset') the correlation matrix to see if it consistent with the one I have in the original dataset

For example, In my date I have the 20% of female and 80% of male, and I want to obtain that they are 50% and 50%.

I proceeded as follows:
- calculating the weight (50/80 for male, 50/20 for female)
- creating a new variable that assigns the value 50/80 to male and 50/20 to female
- running the code "corr soldi donna [fweight=weight]", with weight being the variable which contains the weights for male and female

Anyway, Stata gives me an error stating "may not use noninteger frequency weights", where I am wrong? Is not that the kind of weight I need to do this procedure?

Thanks a lot, best, G.
