get.parsamp {timedeppar} | R Documentation |
Get a sample of lists of constant and time-dependent parameters from inference results of infer.timedeppar
Description
This function produces a sample of parameter sets for past and potentially future time points based on the results of
class timedeppar
generated by Bayesian inference with the function infer.timedeppar
.
For time points used for inference, the sample is a sub-samble of the Markov chain, for future time points of
time-dependent parameters it is a random sample based on the corresponding Ornstein-Uhlenbeck parameters and
constrained at there initial point to the end point of the sub-sample.
Usage
get.parsamp(x, samp.size = 1000, n.burnin = 0, times.new = numeric(0))
Arguments
x |
results from the function |
samp.size |
size of the produced sample constructed from the Markov chain stored in the
object of class |
n.burnin |
number of Markov chain points to omit for density and pairs plots (number of omitted points is max(control$n.adapt,n.burnin)). |
times.new |
vector of time points to predict for. If no time points are provided, sampling is only from the inference Markov chain; if time points are provided, they need to be increasing and start with a larger value than the time points used for inference. In the latter case, time-dependent parameters are sampled for the future points and appended to the inferred part of the time-dependend parameter. |
Value
list of
param.maxpost
: list of constant and time-dependent parameters corresponding to the maximum posterior
solution for inference (no extrapolation to the future).
param.maxlikeli
: list of constant and time-dependent parameters corresponding to the solution with
maximum observation likelihood found so far.
param.list
: list of length samp.size
containing lists of constant and time-dependent parameters;
for time-dependent parameters sub-sample of the Markov chain for past time points,
sample from Ornstein-Uhlenbeck processes conditioned at the initial point for future
time points (see argument times.new
).
param.const
: sub-sample of constant parameters.
param.timedep
: list of sub-samples of time-dependent parameters.
param.ou
: sub-sample of Ornstein-Uhlebeck parameters of the time-dependent parameter(s).
ind.timedeppar
: indices of time-dependent parameters in the parameter lists.
ind.sample
: indices of the stored, thinned sample defining the sub-sample.
ind.chain
: indices of the original non-thinned Markov chain defining the sub-sample.
dot.args
: ... arguments passed to infer.timedeppar
; to be re-used for new
model evaluations.
