WebJul 5, 2024 · The empirical cumulative distribution function (ecdf) is closely related to cumulative frequency. Rather than show the frequency in an interval, however, the ecdf shows the proportion of scores that are less than or equal to each score. In base R, it's easy to plot the ecdf: WebIn R, you can use the punif function to calculate the uniform cumulative distribution function, this is, the probability of a variable X X taking a value lower than x x. This function has the following syntax: punif syntax
