That's (among others) why I wrote -scores-:

* ------------------------------------------
which scores
if _rc ssc install scores

clear*
set obs 100

foreach var of newlist var1-var10{
	gen `var'=  cond(runiform()>.5,.,2)
}

* Version 1:
egen float rownonmissings = rownonmiss(var*)
egen float rowmean = rowmean(var*) if inrange(rownonmissings,7,.)
drop rownonmissings

* Version 2:
scores rowmean2 = mean(var*), nv(7)

* Check:
sum rowmean rowmean2
