Description Usage Arguments Details Value Examples
Evaluate uncertainty in the mixture of distributions of maximums assuming the underlying data generating mechanism is the 2D extremal Poisson process with the Gumbel like intensity function (i.e. the tail length is zero), but without specifying a single threshold. The mixture is across multiple thresholds.

gumbelMaxDistUncert(x, declust_obs, lt_gen,
n_mc, n_boot, progress_tf = TRUE)
|
x |
An S3 object of class |
declust_obs |
(numeric vector) The observed data used by
|
lt_gen |
(numeric scalar) Length of each generated series. The units
(seconds, minutes, hours, etc.) should be consistent with the value of
|
n_mc |
(numeric scalar) The number of samples to draw from the distribution of the maximum |
n_boot |
(numeric scalar) The number of bootstrap replicates of the distribution of the maximum to create. |
progress_tf |
Display a progress bar if TRUE, else not. |
The results of fitting a many Gumbel like 2D extremal Poisson
process are fed into this function. The declustered data are repeatedly
sampled with replacement, and for each resampled data set the distribution
of the maximum is empirically constructed as described in
gumbelMaxDist.gumbel_multi_fit
. The bootstrap replicates of the
mixture of distributions of the maximum may be used to quantify uncertainty
and construct intervals.
An S3 object of class gumbel_max_dist_uncert_multi_thresh
,
which is a list of length n_boot
of S3 objects of class
gumbel_max_dist_multi_thresh
.
