Autocorrelation, Hetroscedastcity and the normality of residuals are being considered as the important diagnostics to examine the credibility of model. If Autocorrelation is examining by DW so up to which level the DW will be sufficient for reliable results?
What measure will used for hetroscedasticity in panel regression?
Chuck A Arize
There are few tests you can use for panel data analysis.
- Panel unit root test.
- random effect or fixed effect ( Hausaman Test)
- Test for heteroskedasticity.
- Serial correlelation tests for long time series.

Regression diagnostics are methods for determining whether a regression model that has been fit to data adequately represents the structure of the data.
