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: WebFirst, we need to create a sequence of probabilities: x_qf <- seq (0, 1, by = 0.01) # Specify x-values for qf function.
