Description Usage Arguments Details
Fill
1 | theta_hier(y, u, n, prior, likelihood, K = 1, chain_init, ...)
|
y |
Numeric, sequence of depedent random variables. May be a matrix. See details. |
u |
Numeric, the threshold. Defaults to quantile(y, 0.90). |
prior |
List. |
likelihood |
Character, either "ferro" or "suveges" (default). |
K |
Numeric, the run parameter for likelihood = "suveges" only. Defaults to K = 1, the model proposed in Suveges (2007). |
... |
Additional arguments passed to mwBASE::mcmc_sampler. |
ord |
Numeric, vector of length R = NCOL(y). Defaults to 1:R. See details. |
The data y is expected to be observed values along an evenly-spaced grid of width 1. If y is an n x R matrix, then it will be collapsed to y = c(y[,ord]). This may be the case when working with multiple realizations from the same process or with specific seasons on a time-series.
The 'classical' option for method produces the estimates given by either Ferro and Segers (2003) or Suveges and Davison (2010). When method == 'bayesian' the likelihoods given in the aforementioned papers are used to produce posterior samples for theta.
