WebDescription. cdfplot (x) creates an empirical cumulative distribution function (cdf) plot for the data in x. For a value t in x, the empirical cdf F(t) is the proportion of the values in x less than or equal to t. h = cdfplot (x) returns a handle of the empirical cdf plot line object. Use h to query or modify properties of the object after you ... WebSimply put, an empirical distribution changes w.r.t. to the empirical sample, whereas a theoretical distribution doesn't w.r.t. to the sample coming from it.
