homoscedasticity
Technical term in statistics and mathematics referring to the property of a set of random variables where all variables have the same finite variance.
In regression analysis, homoscedasticity of the error terms is often assumed.
If homoscedasticity is not satisfied, the estimation of standard errors becomes biased.
Refers to heteroscedasticity, the opposite property where variances are not equal across observations.
Compound of 等 (equal), 分散 (variance), and 性 (property). A direct calque of the English statistical term 'homoscedasticity'.
