deterioration: Time to Cosmetic Deterioration of Breast Cancer Patients

In DPWeibull: Dirichlet Process Weibull Mixture Model for Survival Data

Description

We reused the dataset "deterioration" of the time to cosmetic deterioration of the breast for breast cancer patients provided by the package DPpackage, which is orphaned in CRAN now. The two treatments are radiation alone and radiation coupled with chemotherapy. The event time is either right censored or interval censored.

Usage

data(deterioration)

Format

A data frame with 94 observations on the following 3 variables.

left

a numeric vector giving the left limit of the interval

right

a numeric vector giving the right limit of the interval, -999 stands for right censoring

trt

a numeric vector giving the treatment (0 = radiation only, 1 = radiation plus chemotherapy)
