Re: White's special case heteroskedasticity test
If it is the matter of r^2, how does eviews calculate it's r^2?

Re: White's special case heteroskedasticity test
First of all it is not a special R squared, it is the rsquared obtained from regressing the residuals squared on the fitted values and their squares. It has nothing to do with "special." My statement is not that eviews should magically know what I'm doing either. My point is that conductin...

Re: White's special case heteroskedasticity test
No you misunderstand. The problem is that the specialized white's test where you save the residuals, square them, and then run a regression of residsq on (fitted values)yhat and [(fitted values)^2]yhat^2 is wrong in eviews. As stated before, this test is supposed to mimic the white's test, meanwhile...

Re: White's special case heteroskedasticity test
No you misunderstand, his point is not correct with regards to the test. Because both of these models are supposed to show heteroskedasticity through either the LM statistic or through the use of the F statistic. This test is supposed to mimic the white test that is built in to the program. By exclu...

Re: Weight least squares
I was trying to correct the variance of a model that exhibited heteroskedasticity.

Re: White's special case heteroskedasticity test
When I add the intercept to both eviews and gretl the output from each is identical. It is only with the removal of the intercept that there is a difference.

White's special case heteroskedasticity test
When running a regression and testing for heteroskedasticity using the white test, the degrees of freedom gets eaten up rather quickly. To mitigate this there is a special case in which you can use the fitted values and squares of the fitted values to save on the degrees of freedom. I'm using woolri...

Weight least squares
I have a model that I'm running and I know the weight that I need to add to the model. I want to know how to do it with the menus meaning that I select quick the estimate equation. I have done the weighted least squares the tedious way, but I would like to know how to do it in a faster way. I have l...

Re: dummy and interaction dummy
Do you need help creating dummy variables,
or are you just asking how they function with certain operations with eviews?

How do I save the fitted values for an estimated regression?
I have eviews 7.2 but I do not know how to save the predicted values after running a regression. In gretl there is an option to save the predicted values, and I would like to know how I can do this in eviews. Thanks
