Mean, Variance, Moments and Characteristic Functions

Mean, Variance, Moments and Characteristic Functions. Mean and Variance. p.d.f of a r.v represents complete information about it. quite often it is desirable to characterize the r.v in terms of its average behavior. We introduce two parameters Mean Variance
