Population cdf
WebThe simplest cdf estimator is the empirical cdf -- the ECDF at x is the proportion of the sample at or below x. By Glivenko-Cantelli, if you're sampling at random from the population distribution, then in the limit as n goes to infinity the ecdf converges to the population cdf. Webexample. [f,x] = ecdf (y) returns the empirical cumulative distribution function f, evaluated at x, using the data in y. example. [f,x] = ecdf (y,Name,Value) specifies additional options …
