In parmsurvfit: Parametric Models for Survival Data

Description

Creates histogram of right censored data with the density function of a fitted parametric distribution overlayed.

Usage

plot_density(data, dist, time = "time", censor = "censor", by = "")

Arguments

data	A dataframe containing a time column and a censor column.
dist	A string name for a distribution that has a corresponding density function and distribution function. Examples include "norm", "lnorm", "exp", "weibull", "logis", "llogis", "gompertz", etc.
time	The string name of the time column of the dataframe. Defaults to "time".
censor	The string name of the censor column of the dataframe. Defaults to "censor". The censor column must be a numeric indicator variable where complete times correspond to a value of 1 and incomplete times correspond to 0.
by	The string name of a grouping variable. If specified, the function plots each group individually along with the plot for all groups together. Variable can contain logical, string, character, or numeric data.

Examples

data("rearrest")
plot_density(rearrest, "exp", time = "months")
plot_density(rearrest, "weibull", time = "months", by = "personal")
