-viewsource _growtotal.ado- shows that treating missings as 0 is exactly what -egen, rowtotal()- does. Nick [email protected] David Bell You have surmised that -egen newvar = rowtotal(var1 var2)- treats missing values as zero. I do not believe this is strictly correct. The command just sums the values that it has (thus not using a variable in a sum is the same as treating it as zero). This is why I always use -rowmean- instead of -rowtotal-. Thus when there is a missing value, you get the mean of the remaining values (they are not treated as zeros).
