In SPSS, when activate the weight variable, the data case number get multiplied by number in weight and such way no need to apply weight for each analysis. I wonder if possible to apply the same concept in STATA, by replicating the data cases by the number of weight variable and then no need to apply weights to each analysis seperately. Such way assuming in a data of 100, with a frequency weight of 3. Then i automatically generate a data where each case replicated 3 times with final data file containing 300 cases.
