## Calculate Flood/Rainfall Frequency from cumulative distributionfunction (CDF) of the distribution

Specifically, we will use the cumulative distribution function (CDF) of the fitted distribution to calculate the annual exceedance probability (AEP), or the probability that the event is equaled or exceeded in any single year. For example, considering a 200,000 cfs level, the exceedance probability is calculated in the following way: Exceedance_P = P{X≥200} = 1 … Read more
