Hi all:

While using madfuller to test panel unit root,
I use the example provided by this package.
Those commands I use are following:

tsset country year, yearly
madfuller rgdppc if country<11, lags(2(2)8)

But I got error message like 'variable __000001 not found' or ' variable
year not found'
Does anyone have same experience like this?
Or the commands I set are wrong?

Thanks for any advice,
