This can be done using the empirical cumulative distribution function (EDF, or ECDF) of the data. It is denoted by P and is defined at a point as the proportion.

Similarly, most distributions have a mean, variance and so on. Definition: A function from set of all cdfs to real line is called a statistical functional.

The empirical distribution function (EDF) is the “data analogue” of cdf of a random variable. The EDF is defined as: F ˆ n ( ...
