rp2prob(retper, npy)
prob2rp(prob, npy)

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 = 1 / (npy (1-p))

where npy is the mean number of events per year (block), p is the probability of non exceedance.

Value

Returns a table with mean numbers of events per year, return periods and probabilities of non exceedance associated.
