Dear readers,
After I used the command "xtunitroot fisher Female, dfuller lags(1)"
the following error showed up
performing unit-root test on first panel using the syntax
dfuller Female, lags(1)
returned error code 2000
r(2000);
error . . . . . . . . . . . . . . . . . . . . . . . . Return code 2000
no observations;
You have requested some statistical calculation and there are
no observations on which to perform it. Perhaps you specified
if or in and inadvertently filtered all the data.
I do have observations for the variable Female. After the error, I tried to do it again after dropping all missing values of Female, but that didn't work either.
I used the -xtunitroot fisher- because I have unbalanced panel data.
I need to know if certain variables like Female (gender) are stationary because I need the Granger-causality test to test if there is reversed/backward causality in my dataset.
I'm looking forward to your replies.
Victoria
