draw_pred {lgpr} | R Documentation |
Draw pseudo-observations from posterior or prior predictive distribution
Description
Draw pseudo-observations from predictive distribution.
If pred
contains draws from the component posterior (prior)
distributions, then the output is draws from the posterior (prior)
predictive distribution. If pred
is not specified, then
whether output draws are from prior or posterior predictive distribution
depends on whether fit
is created using the lgp
option prior_only=TRUE
or not.
Usage
draw_pred(fit, pred = NULL)
Arguments
fit |
An object of class lgpfit that has been created
using the |
pred |
An object of class Prediction, containing
draws of each model component. If |
Value
An array with shape S x P
, where S
is the number of
draws that pred
contains and P
is the length of each
function draw.
Each row s = 1, \ldots, S
of the output is one vector drawn from the
predictive distribution, given parameter draw s
.
