(uncountable, usually) A property of a set of random variables such that each variable has the same finite variance.
Preliminarily, the weak homoscedasticity of the two classes has been tested:[…].

1989, AW Storey, “The freshwater mussel, Westralunio carteri Iredale, as a biological monitor of organochlorine pesticides”, in Australian Journal of Marine and Freshwater Research, volume 40, number 6, page 587:Unlike OLS^([Ordinary Least Squares]) regression, logistic regression does not assume linearity of relationship between dependent and independent variables; does not require normally distributed variables; does not assume homoscedasticity; and in general has less stringent requirements.
2010, Min Gyo Koo, Island Disputes and Maritime Regime Building in East Asia, footnote, page 46:Thus, Glejser's test also rejects the hypothesis of homoscedasticity.
