Since this is posted in statistics discipline ( pdf and cdf have other meanings too): This matlab function returns the empirical cumulative distribution function (cdf), f, evaluated at the points in x, using the data in the vector y. The cumulative distribution function, cdf, or cumulant is a function derived from the probability density function for a continuous random variable.

If we have a random sample of size n from a distribution then we often estimate the cdf f of that distribution by the empirical distribution function.

For a discrete distribution, the cdf can be expressed as. For the second way, use the conditional formula (shown below) with the original distribution x ~ u (0 formula review. We use cookies to improve your navigation experience. Cdfdist,x gives the probability that an observed value will be less than or equal to x.
