Heteroscedasticity - Wikipedia

In statistics, a vector of random variables is heteroscedastic (or heteroskedastic; from Ancient Greek hetero "different" and skedasis "dispersion") if the variability of the random disturbance is different across elements of the vector. Here, variability could be quantified by the variance or any other measure of statistical dispersion.Thus ,heteroscedasticity, is the absence of homoscedasticity.
