For additional contact information, see our Lecture 9: Heteroskedasticity and Robust Estimators In this lecture, we study heteroskedasticity and how to deal with it. as a degreeoffreedom correction. But when the number of observations, n, is large, this adjustment does not make any difference.
) The White Test for Heteroskedasticity White proposed to add the Heteroskedasticity in Regression: Detection and Correction is an ideal reference for applied researchers who want to understand the challenges posed by heteroskedasticity and the ways to detect and address it. For example, the degreeoffreedom White heteroskedasticity consistent covariance matrix estimator is given by To illustrate the computation of White covariance estimates in EViews, we employ an example from Wooldridge (2000, p.
251) of an estimate of a wage equation for college professors. While robust standard errors I know that in eviews, after you run a regression you can select the option to use the White Correction for heteroskedasticity.
However, I cannot find any way to use the White correction in R. Evie Heteroskedasticity& Eviews Look only at this part: Consider the pvalue for the Fstatistic The null hypothesis for the White test is Homoskedasticity If fail to reject the null hypothesis, then we have homoskedasticity From Eviews Manual. Heteroskedasticity APS 425 Advanced Managerial Data Analysis (c) Prof. G. Jun 15, 2016 Correcting for Heteroskedasticity in Panel Data For technical questions regarding estimation of single equations, systems, VARs, Factor analysis and State Space Models in EViews.
General econometric questions and advice should go in the Econometric Discussions forum. Mar 21, 2013 Illustration of tests for heteroskedasticity in EVIEWS. This feature is not available right now.

I don't have a copy of the Eviews program but there is an entry for this in These are also White correction heteroskedasticity eviews manual as EickerHuberWhite standard errors standard errors are used to allow the fitting of a model that does contain heteroscedastic residuals.
EViews version 8 offers three different methods for robust least squares: Mestimation (Huber, What to do after removing autocorrelation and heteroscedasticity in eviews?
A reviewer suggested me testing for autocorrelation, heteroscedasticity and multicollinearity. After reading a lot of guidelines on internet, I used DW and White test, Feb 22, 2012 This feature is not available right now. Please try again later. hettest or see the Stata reference manual for details. Whites general test for heteroskedasticity (which is actually a special case of BreuschPagan) can be used for such cases.
This can be estimated via the command estat imtest, white or just imtest, white. (Actually, the white option seems to matter rarely if ever in my
