tsRandom Variability For any random variable X , the variance of X is the expected value of the squared difference between X and its expected value: Var[X] = E[(X-E[X])2] = E[X2] - (E[X])2 . (The second equation is the result of a bit of algebra: E[(X-E[X])2] = E[X2 - 2⋅X⋅E[X] +(E[X])2] = E[X2] - 2⋅E[X]⋅E[X]...
