I have idea of physical signif of var(x),cov(x) but can't get derivations of equation.
Hi all,
I understood the facts that variance indicate the spread in random variable and covariance shows correlation between 2 r.v s etc. But I cannot imagine how we are arriving at their equations. Also what is the significance of nth moment etc?
