同方差性in statistics (= the science of using information discovered from studying numbers), a situation in which all the variables (= things that can change) in a sequence (= a series of related things) are equal
We test for homoscedasticity by use of the Breusch-Pagan test. 我们用布鲁薛—培根检验法来检验同方差性。
In several cases, the homoscedasticity assumption could not be met.
It is possible to estimate this model to ensure homoskedasticity.
