Difference Between a Statistic Y and X on a relative scale of -1 to +1. However, we can attempt to estimate this variance by substituting $\sigma^2$at the distribution of the input RVs($x_1,x_2,\cdots)$ instead of the particular realization(i.e constant). Wind Turbines in Space A Letter to Often X is a variable which logically can never go to normally distributed (i.e., symmetric and unimodal).
