st: Tips on working with multiple waves RAND HRS |

Dear statalist, I am currently working with a RAND HRS dataset consisting of 8 waves of observations. This implies that for a single variable, such as income, the dataset consits of 8 variables of observations, for instance r1income, r2income,..., r8income. This works fine when considering the effects seperately, i.e. if I want to calculate mean in wave 1 and 8, but it is a bit comprehensive when one wants to retrieve the mean of the full dataset. Additionally I have variables that weight the observations, r1wtresp,...r8wtresp. My question is whether you have some tips on how to calculate for instance the weighted mean of the full dataset of 8 waves. I know that when I calculate the sample mean per wave I can use the command mean(r1income) [pweight = r1wtresp] mean(r2income) [pweight = r2wtresp] mean(r3income) [pweight = r3wtresp] .. etc But how do I do it when I want the mean of all observations (something like stacking all variables under eachother and then treating it as one variable). Thanks! Regards, D. Sneijder * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
