A PDF fit for an empirical data distribution can be discovered in four steps: Compute density and weights from a histogram. The first step is to flatten the data into an array and create the histogram by grouping observations into bins and counting the number of events in each bin.

WebbThe cdf is an increasing step function that has a vertical jump of at each value of x equal to an observed value.
