Ivica,

You've renamed your evaluator program nlsuraidsmmmm, but you are telling -nlsur- to look for an evaluator program called nlsuraidsmesommmm:


* -nlsur-
nlsur aidsmesommmm @ w1 w2 w3 w4 w5 lnp1 lnp2 lnp3 lnp4 lnp5 lnp6 lnexp,
///


When I change the -nlsur- call to

   nlsur aidsmmmm ...

it works fine (using fake data).

Subject: Re: st: RE: RE: -nlsur- AIDS

Ivica,

You forgot to define g61 through g66.  Even though we drop the last
expenditure share equation in estimation, we still need those gamma
parameters to calculate the price index.  After the line

    scalar -`g51'-`g52'-`g53'-`g54'-`g55'

you need to add

    tempname g61 g62 g63 g64 g65 g66
    scalar `g61' = `g16'
    scalar `g62' = `g26'
    scalar `g63' = `g36'
    scalar `g64' = `g46'
    scalar `g65' = `g56'
    scalar `g66' = -`g61' - `g62' - `g63' - `g64' - `g65'
		
Also, this line:

    scalar `b6' = 1-`b1'-`b2'-`b3'-`b4'-`b5'

isn't right; the betas should sum to zero, not one, so that line should
be

    scalar `b6' = -`b1'-`b2'-`b3'-`b4'-`b5'

(but in fact you don't even need the last beta to evaluate just the
first K-1 expenditure shares, so `b6' isn't even used.)

Nick, I've corrected what you suggested, but it still doesn't work. Of

Here's the corrected code which still doesn't work and returns the
