surv_summary: Summary statistics based on parametric distribution

In parmsurvfit: Parametric Models for Survival Data

Description

Estimates various statistics, including median, mean, standard deviation, and percentiles of survival time given that the data follows a specified parametric distribution.

Usage

surv_summary(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 a 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, returns summary statistics for each group. Variable can contain logical, string, character, or numeric data.

Examples

data("rearrest")
surv_summary(rearrest, "lnorm", time = "months")
surv_summary(rearrest, "weibull", time = "months", by = "personal")
