greta.censored: Censored Distributions for greta

Overview

greta.censored is an R package that extends greta to support the following distributions with right, left, and interval censoring:

  • Normal
  • Log-Normal
  • Student’s T
  • Gamma
  • Exponential
  • Weibull
  • Pareto
  • Beta

Installation

You can install the stable version of greta.censored from CRAN with:

install.packages("greta.censored")

Alternatively, you can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("mtwesley/greta.censored")

Usage

Here are some examples demonstrating how to use the main functions of the greta.censored package:

Example 1: Censored Normal Distribution 

library(greta)
library(greta.censored)

# Define the parameters
mean <- as.greta_array(0)
sd <- as.greta_array(1)
is_censored <- as.greta_array(c(0, 1, 0))
censor <- "right"
lower <- -Inf
upper <- 1

# Create the censored normal distribution
dist <- normal_censored(mean, sd, is_censored, censor, lower, upper)

# Print the distribution
print(dist)

Example 2: Censored Log-Normal Distribution 

library(greta)
library(greta.censored)

# Define the parameters
meanlog <- as.greta_array(0)
sdlog <- as.greta_array(1)
is_censored <- as.greta_array(c(0, 1, 0))
censor <- "left"
lower <- 0
upper <- Inf

# Create the censored log-normal distribution
dist <- lognormal_censored(meanlog, sdlog, is_censored, censor, lower, upper)

# Print the distribution
print(dist)
