st: RE: Parsing variable list into dependent and independent variables (logit)

["Feiveson, Alan H. (JSC-SK311)" <alan.h.feiveson@nasa.gov>]

Leif - Try the syntax below:

Note you should also initialize
local indepvars ""

before the loop. If you're working with strings, it's usually better to
not use "=" signs.


local indepvars "`indepvars' `indepvar'"

Subject: st: Parsing variable list into dependent and independent
variables (logit)

I am trying to run the mylogit.ado program (below) to parse a variable
list and run logit regression.  However, there is an exception being
thrown at run-time which is called "+ invalid name."  

Example usage is:

mylogit bloodpress age sexfem


----------------------------------

program define mylogit,eclass
  version 10
  syntax [varlist]
  local ncol:word count `varlist'
  local depvar:word 1 of `varlist'
  forv i=2(1)`ncol' {
  local indepvar:word `i' of `varlist'
  local indepvars `indepvars' + "`indepvar'"
  }
  logit `depvar' `indepvars'
end
