- (statistics) A property of a set of random variables such that each variable has the same finite variance.

- Before analysis, homoscedasticities of sample variances were assessed by Cochran's C and Bartlett's Box tests.

- 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.

- Preliminarily, the weak homoscedasticity of the two classes has been tested: […] .

- Thus, Glejser's test also rejects the hypothesis of homoscedasticity.
- (statistics): heteroscedasticity
