## S3 method for class 'gumbel_pot_fit'
gumbelNYear(x, N)
## Default S3 method:
gumbelNYear(x, thresh, N)
|
x |
An S3 object of type |
N |
(numeric scalar) The N in N-year return value. This is a bit of a
misnomer since the unit of time does not have to be years. The function
can calculate N-second, N-minute, N-hour, etc. return values as well. In
fact, the unit of time is the same unit of time passed in for the
|
thresh |
(numeric scalar) The threshold |
Solves the equation
\int_{y_N}^∞\int_0^1λ(t, y)dtdy = \frac{1}{N}
where λ(t, y) is given in the documentation for gumbelMLE
An S3 object of class gumbel_N_year_val
with elements
$par
numeric vector of length 2 containing the location and scale parameters, respectively of the 2D extremal Poisson process used to calculat the return value
$thresh
The threshold
$N
The value inputted for N
$N_year_val
(numeric scalar) The return value
