      Before analysis, homoscedasticities of sample variances were assessed by Cochran's C and Bartlett's Box tests.
    • 2010, Min Gyo Koo, Island Disputes and Maritime Regime Building in East Asia[1], footnote, page 46:
      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, Francesca Greselin, Salvatore Ingrassia, “Weakly Homoscedastic Constraints for Mixtures of t-Distributions”, in Andreas Fink, Berthold Lausen, Wilfried Seidel, Alfred Ultsch, editors, Advances in Data Analysis, Data Handling and Business Intelligence[2], Springer, page 225:
      Preliminarily, the weak homoscedasticity of the two classes has been tested: [] .
