Error with code, unsure of issue

[Milind Parwani]

Hi all,

I'm attempting to run this code:

* ARDL Models
forvalues p=1/4{
forvalues q=1/4{
qui reg dunemp_JPN 1(1/`p').dunemp_JPN 1(0/`q').dinf_JPN if year>=1946 & year<2016
qui predict res_`p'_`q' if e(sample)
di in ye "*******************************"
di in ye "Model with ARDL(`p',`q'):"
estat bgodfrey, lag(4)
estat ic
di in ye ""
di in ye ""
}

}

I've seen this same syntax in my lectures yet when I try to run the code stata outputs "1 is invalid name"
I have recently just started using Stata as part of an econometrics module so I'm unsure of how it works.

Thanks

I think you need L for lag not the numeral 1. Lower case l looks all too similar to numeral 1. So

qui reg dunemp_JPN L(1/`p').dunemp_JPN L(0/`q').dinf_JPN if inrange(year, 1946, 2015)

where I've also added use of inrange().

Wow that was a embarrassing error, glad it was that simple. Thank you for your help Nick!
