Why does a shorter string of lights not need a resistor?

Only if there is heteroskedasticity will the "normal" standard error be inappropriate, which means that the White Standard Error is appropriate with or without heteroskedasticity, that is, even when your model For any non-linear model (for instance Logit and Probit models), however, heteroscedasticity has more severe consequences: the maximum likelihood estimates of the parameters will be biased (in an unknown direction), as

Heteroskedasticity Robust Standard Errors Excel where the elements of S are the squared residuals  from the OLS method.

While the OLS point estimator remains unbiased, it is not "best" in the sense of having minimum mean square error, and the OLS variance estimator v O L S [ β Heteroskedasticity Robust Standard Errors R If your weights are right, however, you get smaller ("more efficient") standard errors than OLS with robust standard errors. pp.59–82. http://stats.stackexchange.com/questions/452/always-report-robust-white-standard-errors SOme people just delete them to get better results, it's nearly the same when using robust standard errors, just in another context.

Unlike the asymptotic White's estimator, their estimators are unbiased when the data are homoscedastic. check over here Alternative estimators have been proposed in MacKinnon & White (1985) that correct for unequal variances of regression residuals due to different leverage.
