Dear Statalisters,

I encouter some problem when estimating a survey probit model. Each
independent variable will be interacted with the variable "group". So,
my command is like this:

. svyset [pw=pw1]
. xi:svy:probit y*x1 | x2*x3*x4          ,

where x1,x3,x4 are continuous  x2 is categorical.

The system gives error information as:

initial vector: duplicate entries for o._Igroup_1 found
an error occurred when svy executed probit

I guess it means there are duplicate dummies in the command. But not
sure. Any comments or suggestions will be helpful. Thank you!

Best wishes,
