What useful tool allows us to refine?
If you are sampling from the same population and your estimate of p(x) is (x)/n (n=sample size) then the result of repeated random samples from the population will converge to the population value according to the central limit theorem. The underlying population doesn't need to be normally distributed.
you are right..i must study on this..
thank you very much
