Return Periods Tools {POT} | R Documentation |
Compute return period from probability of non exceedance and vice versa.
rp2prob(retper, npy)
prob2rp(prob, npy)
retper |
The return period. |
prob |
the probability of non exceedance. |
npy |
The mean Number of events per year (block). |
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.
Returns a table with mean numbers of events per year, return periods and probabilities of non exceedance associated.
