psc

The goal of psc is to compare a dataset of observations against a parametric model

Installation

You can install the development version of psc from GitHub with:

# install.packages("devtools")
devtools::install_github("richJJackson/psc")

Example

This is a basic example which shows you how to solve a common problem:

library(psc)
library(survival)
## basic example code

### Load model
data("surv.mod")

### Load Data
data("data")

### Use 'pscfit' to compare
surv.psc <- pscfit(surv.mod,data)
