Invalid Syntax Error During Looping

[Guest]

Hi,

I am trying to run a non-parametric regression to calculate downward mobility. Whenever I try to run the following command I get an error stating invalid syntax.

Code:
forval h=1/`r(max)' {
forvalues f=90(-10)50 {
foreach var of varlist child_wage-head_wage {
qui reg `var' if group==`h' & head_wage>`f'
outreg2 using "DonwardRankMobility.xls", replace
}
}
}

I would check that r(max) really is there to use at the start of the loop using

return list

Not the issue, but your regressions are nested. I guess that's deliberate. All they do is produce mean outcomes, which you could also do with summarize.

Thank you for this, r(max) was causing the problem but I need to do it for the variable group which takes 8 values.
The code forval h=1/`1(1)8 does not seem to work.

try with forval h=1/8 instead, it may work
