“Should have told the student to change their study to embrace the heteroscedasticity in the data-- maybe some hypotheses about the differences in rate of absorption of syrup by pancakes, crepes, and waffles.”
“The histograms of calibration residuals were examined for possible heteroscedasticity, but were found to pass a chi2 test for gaussian characteristics at reasonably high levels of significance NH, 95% level; NINO3, 99% level.”
“The histograms of calibration residuals were examined for possible heteroscedasticity, but were found to pass a x2 test for gaussian characteristics at reasonably high levels of significance NH, 95% level; NINO3, 99% level.”
“Thus, the here presented procedure works well under biologically realistic scenarios of unbalanced group sizes, non-normality and heteroscedasticity.”
“ProudCapitalist: I wonder how the mainstream econometric economist comments this data: That heteroscedasticity has su ... jb1122: Current: Robert Murphy refuted this piece in november, do a blog search for it. ...”
“I wonder how the mainstream econometric economist comments this data: That heteroscedasticity has suddenly soared?”
“However, they fail to reject the null of no correlation (or heteroscedasticity) within countries.”
“The procedure does not just correct for heteroscedasticity.”
“Normality of residuals and absence of heteroscedasticity were verified, otherwise logarithmic or square root transformations were applied to the dependent variable.”

sionnach Indeed, some of us have frittered away far too much of our professional careers attempting to model heteroscedasticity in some useful fashion. But lexylou makes a good point -- there are some scenarios where accurate characterization of variability may be at least as important as getting the average behavior down. One example would be in establishing the operating characteristics of a particular assay, where a good understanding of both bias and precision (both intra- and inter-assay variability) is likely to be important.

lexylou also: dh and jm also miss the vital fact that heteroscedasticity can be modeled (e.g. mixed models, multilevel models, etc.) and may in fact be of substantive interest in its own right. May 12, 2009
sionnach It would appear that JM has been misled by unscrupulous scoundrels. Feb 1, 2009
jmjarmstrong JM has been assured that heteroscedasticity can be overcome by transforming your data in an appropriate manner.

dhuber ...uneven variances between variables.
A bad thing to have if you are trying to meet the assumptions of certain parametric tests. But, this can be overcome by transforming your data in an appropriate manner. Nov 15, 2007
