nonexceeds {lmomco} | R Documentation |
This function returns a vector nonexceedance probabilities.
nonexceeds()
A vector of selected nonexceedance probabilities useful in assessing the “frequency
curve” in hydrologic applications (noninclusive). The nonexceedance probabilities
extend further into the right-hand tail of the “distribution” to the 0.996 and 0.998
nonexceedance probability values as these are equivalent to the 250- and 500-year events
respectively. The relation between annual recurrence interval and nonexceedance
probability (when annual data are analyzed) is
F = 1 - frac{1}{T} mbox{,}
where T is the T-year event.
