About this document
Understanding Variance in Heterogeneous Data by gillnumber22 is a document available to read on EtoBox.
The document contains mathematical expressions for calculating the variances of variables X1i, X2i, and the difference between X1i and X2i. It shows that the variances of X1i and X2i are equal to the variance of their error terms ε1i and ε2i, respectively. It also shows that the variance of the difference X1i - X2i is equal to the variance of the difference between their error terms ε1i - ε2i. The document asks if this is correct and asks how choosing non-homogeneous pairs can neutralize differences between
