Webb4 jan. 2024 · You sample from the CDF first by inverting it. The inverse CDF is called the quantile function; it is a mapping from [0,1] to the domain of the RV. You then sample random uniform RVs as percentiles and pass them to the quantile function to obtain a random sample from that distribution.
