Marginal variation
WebLaw of total variation For any regression model involving a response y 2Rand a covariate vector x 2Rp, we can decompose the marginal variance of y as follows: var(y) = var xE[yjx = x] + E xvar[yjx = x]: IIf the population ishomoscedastic ,var[yj x] does not depend on so we can simply write var[yjx] = ˙2, and we get var(y) = var xE[yjx] + ˙2.
