WebThus, the probability density function (pdf) of a Gaussian distribution is a Gaussian function that takes the form: Although the graphs of all Gaussian distributions share the same general bell shape, the parameters of the function affect the overall shape of the graph: ... The Z table in the figure below is a cumulative from mean Z table ... WebThe empirical distribution function is an estimate of the cumulative distribution function that generated the points in the sample. It converges with probability 1 to that underlying distribution, according to the Glivenko–Cantelli theorem. A number of results exist to quantify the rate of convergence of the empirical distribution function to ...
