Got you. I'll write heteroskedastic when others agree to honour
etymology and talk about kylikal variations. 

Econometrica which published this did not see the light and change its
name to Econometrika. 

As I recall, heteroscedastic was coined by Karl Pearson who changed his
own name from Carl to Karl and founded Biometrika, so consistency's the
hobgoblin of little minds. 



Just referring to McCulloch's second last paragraph. 
A better counter-argument to him would be c is sclerosis or in sceptic.
(Yes, I know Americans spell sceptic with a k).

I see no Latin here. The root elements of heteroscedasticity are Greek

DE SOUZA Eric replied to Austin Nichols

Ah--interesting, and I applaud the terminology change!  Robust is
certainly an ambiguous description, as is sandwich, whereas het-robust
and cluster-robust are fairly specific (esp. when combined with a
reference to the literature).  Maybe new vce() term hrobust or
hetrobust?  Please don't make us spell out heteroskedasticity...  ;)

McCulloch, J.H. 1985. "On Heteros*edasticity." Econometrica 53(2): 483.

Pace McCulloch, in Classical Latin the "g" is hard and the "c" sounds
like "k". 
Although in Ecclesiastical Latin, the "g" is soft and the c has a "ch"
