Hello,
I've got a panel data set with 200 banks, with data from 20022016 with varying degrees of data availability. On average there is about 8.5 years of data available per bank. I've got a dependent variable: Default risk. And several explanatory variables: Board Characteristics for each bank. Plus various control variables.
Now I was wondering how I should go about testing for serialcorrelation and heteroskedasticity. I've already read this https://www.stata.com/support/faqs/s...tocorrelation/ but that is not entirely what I am looking for as it is unclear to me what is exactly happening. I would like to manually run tests for serial correlation and heteroskedasticity.
I've done a BreuschGodfrey test for serial correlation before but not on a panel dataset, just on time series. I this also suitable for panel data? And how would I perform this test for panel data?
Similarly, I've done a BreuschPagan test for heteroskedasticity before, but never on panel data, is this suitable for panel data?
Some help would be greatly appreciated, as I am new to panel data analysis.
Kind regards,
Niels
