Country-specific time trend in xtivreg2

[Clara Weber]

Hello!

I am doing a 2SLS estimation using the xtivreg2 command. I want to include a country-specific time trend, however, when I include c.year#i.country into the command, I get the following error: "cyear#i: operator invalid"

Am I doing something wrong?
Or is there a way to generate the time trend mannually and then include it in the xtivreg2 command?

Thanks!

Best regards

xtivreg2 is from SSC, as you are asked to explain (FAQ Advice #12).

xi: xtivreg2 ... i.country|year

Better advice: Use a command that supports factor variables, such as the official xtivreg command.
