conditional logit with DC

Hi,

I am running a logit on a fairly large database (2500 individuals and 620 possible choices). I am using the discrete choice application in gauss and it seems to run forever without converging and without giving me any error message. Any idea of what may be possibly going on?

The code is here:

new;
cls;
library dc;

//Load Data
chdir /Users/matteobobba/Dropbox/COMIPEMS/Codes;
//chdir /Users/matteobobba/Dropbox/Search_Schooling/Estimation/Matteo;
load y[1396437,3] = datamatrix_1opt.txt;

//Step One: dcControl structure //Declare dcControl structure
struct dcControl dcCt;
//Initialize dcControl structure
dcCt = dcControlCreate();

//Step Two: Describe data names
dcSetYVar(&dcCt,y[.,2]);
//Dependent variable
dcSetYLabel(&dcCt,"mode");
dcSetCategoryVarLabels(&dcCt,"choiceno");
//Category Labels
dcSetCategoryVar(&dcCt,y[.,1]);
dcSetYCategoryLabels(&dcCt,"y[.,1]'");

//Attribute variables
dcSetAttributeVars(&dcCt,y[.,3]);
dcSetAttributeLabels(&dcCt,"bg");

//Turn off constant
dcSetConstant(&dcCt,"off");

//gm because including attributes
g1 = { .1 };

mask = {1};
dcCt.startValues = pvPackmi(dcCt.startValues, g1' , "g1" , mask', 3);
//dcCt.startValues = pvPackmi(dcCt.startValues, b , "b", mask , 2);

//Step three: Declare dcOut struct
struct dcout dcout1;

//Step Four: Call ConditionalLogit
dcout1 = conditionalLogit(dcCt);

 

//Print Results
call printDCOut(dcOut1);
