nonexceeds: Common Nonexceedance Probabilities

Description

This function returns a vector nonexceedance probabilities.

Usage

nonexceeds()

Value

• 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.
