predictive_interval.blrmfit: Posterior predictive intervals

In OncoBayes2: Bayesian Logistic Regression for Oncology Dose-Escalation Trials

Posterior predictive intervals

Description

Posterior predictive intervals of the model.

Usage

## S3 method for class 'blrmfit'
predictive_interval(object, prob = 0.95, newdata, ...)

Arguments

object	fitted model object
prob	central probability mass to report, i.e. the quantiles 0.5-prob/2 and 0.5+prob/2 are displayed. Multiple central widths can be specified.
newdata	optional data frame specifying for what to predict; if missing, then the data of the input model object is used
...	not used in this function

Details

Reports for each row of the input data set the predictive interval according to the fitted model.

Value

Matrix with as many rows as the input data set and two columns which contain the lower and upper quantile corresponding to the central probability mass prob for the number of responses of the predictive distribution.

Examples

## Setting up dummy sampling for fast execution of example
## Please use 4 chains and 100x more warmup & iter in practice
.user_mc_options <- options(
  OncoBayes2.MC.warmup = 10, OncoBayes2.MC.iter = 20, OncoBayes2.MC.chains = 1,
  OncoBayes2.MC.save_warmup = FALSE
)
