Philip,
You can do it with dummy variable for sample 1 (or 2): identify your sample 1 (or 2) with that dummy by cross multiplying your variables. Then put both of your equations (and samples) into one, run your regression and test coefficients of sample1b1= the coefficient of sample2b1, or you can use suest command: check the help link for the chain of commands to use it: gives the same results of the above application.

```Hello Statausers,
I have a simple query. I am new to stata. So, please help me in this regard.
I want to test the equality of coefficients. I have two identical
equation for two samples with same varibles. I want to test whether
coefficients are significnatly different or not.

Y=constant+b1(x1)+b2(x2)+b3(x3)..........eqn (1)
Y=constant+b1(x1)+b2(x2)+b3(x3)..........eqn (2)

I want to test b1(x1) of first equation=1(x1) of second equation

What is the command and how should i implement.

Thanks in anticipation.

Best,
Philip
