loo.angmcmc {BAMBI} | R Documentation |
Leave-one-out cross-validation (LOO) for angmcmc objects
Description
Leave-one-out cross-validation (LOO) for angmcmc objects
Usage
## S3 method for class 'angmcmc'
loo(x, ...)
Arguments
x |
angmcmc object. |
... |
additional model specific arguments to be passed to waic from loo. For example, |
Details
Note that loo.angmcmc calls loo for computation. If the likelihood contribution of each data
point for each MCMC iteration is available in object
(can be returned by setting return_llik_contri = TRUE
)
during fit_angmix call), loo.array
is used; otherwise loo.function
is
called. Computation is much faster if the likelihood contributions are available - however, they are very
memory intensive, and by default not returned in fit_angmix.
Examples
# illustration only - more iterations needed for convergence
fit.vmsin.20 <- fit_vmsinmix(tim8, ncomp = 3, n.iter = 20,
n.chains = 1, return_llik_contri = TRUE)
library(loo)
loo(fit.vmsin.20)
