Return Periods Tools: Converts Return Periods to Probability and Vice Versa
Description
Compute return period from probability of non exceedance and vice versa.
Usage
rp2prob(retper, npy)
prob2rp(prob, npy)
Value
Returns a table with mean numbers of events per year, return periods
and probabilities of non exceedance associated.
Arguments
retper
The return period.
prob
the probability of non exceedance.
npy
The mean Number of events per year
(block).

Details
The return period is defined by:
$$T = \frac{1}{npy (1-p)}$$
where \(npy\) is the mean number of events per year (block), \(p\)
is the probability of non exceedance.
