add_pred_draws_car1: Generate predictions for CAR(1) model

In bentrueman/bgamcar1: Fit Bayesian GAMs With CAR(1) Errors To Censored Data

Generate predictions for CAR(1) model

Description

Generate predictions for CAR(1) model

Usage

add_pred_draws_car1(
  input,
  object,
  type = "epred",
  car1 = TRUE,
  draw_ids = NULL,
  ...
)

Arguments

input	A dataframe for which to generate model predictions.
object	A brms model object.
type	For type = epred, draws are from the expectation of the posterior predictive; fortype = prediction, draws are from the posterior predictive.
car1	Logical. Add CAR(1) errors?
draw_ids	Draw IDs from model object. If NULL (the default), all draws are used.
...	Argument passed on to tidybayes::add_epred_draws()

Value

A dataframe of the type generated by tidybayes::add_epred_draws().

Examples

library("brms")
seed <- 1
data <- read.csv(paste0(system.file("extdata", package = "bgamcar1"), "/data.csv"))
fit <- fit_stan_model(
   paste0(system.file("extdata", package = "bgamcar1"), "/test"),
   seed,
   bf(y | cens(ycens, y2 = y2) ~ 1),
   data,
   prior(normal(0, 1), class = Intercept),
   car1 = FALSE,
   save_warmup = FALSE,
   chains = 3
 )
add_pred_draws_car1(data, fit, car1 = FALSE, draw_ids = 1234)
