From the given formulae of sample variances which is biased estimator of a^2 and why?
S^2 = Sum ( x - x )^2 , s^2 = Sum ( x - x )^2
n-------------, ------------------- n - 1
I can't post the exact equation in a statistical manner but Please I need the whole equation to be solved step by step. Its urgent. Thanx.
