Hi,

Can you test panel data for heteroskedacity? I can't find the option to run White's test.

Thanks

Thanks Gareth that really helps.

Do you have to have data at regular intervals, for example could i have 2001, 2003, 2005, 2006, 2007, 2008?

Also what is the minimum number of observations required to run White Heteroskedacity cross terms test?

Many Thanks
Jen

Hi,

I have time series data for 2001, 2003, 2005, and 2007, which workfile structure type do I select?

I have selected unstructured/undated but it does not seem to be working.

What is the minimum number of observations needed for time series data?

Many Thanks,
Jen
