Have you tried replacing the first line with: forv i = 1/5{ You don't need a foreach loop here if you're just interested in looping over the values of a categorical variable.

Sizep5 is a variable consisting of numbers from 1 to 5 (1 small companies, 5 large companies). Timeyear is the time variable, 1975 to 2012. I am trying the following: > > > . foreach i of sizep5 1/5 { > 2. forvalues t = 1975/2012 { > 3. replace sizebmp5=1`i' if bm<bm4 & sizep5==`i' & timeyear==`t' > 4. } > 5. } > > However Stata says invalid syntax. I guess the problem is with sizebmp5=1`i' -> 1 stands for the first condition bm<bm4 (I will change this condition manually and then switch to 2 and so on). With `i' I want the variable signalling the corresponding sizep5 portfolio. Because this variable changes from 1 to 5, I need the term `i'; I also tried 1_`i' but it did not work. > > Any suggestions to solve this problem? > > Many thanks in advance. > > Thx, Fabian > > * > * 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/ * * 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/
