Hello,
I use Stata 14. I have a panel dataset. I want to estimate for each id/country in the panel dataset.
The syntax of -mswitch- is

Code:
mswitch dr depvar [nonswitch_varlist] [if] [in] [, options]
While the syntax allows for “if”, when we estimate the command like this,
Code:
mswitch dr gcf if id==1, switch(gds)
Stata returns the following:"
sample may not include multiple panels
r(459);
Any help on how to estimate mswitch for each id will be greatly appreciated. I have given the following dataex.

Code:
clear all
input year gcf gds id
