bcdata: Breast Cosmesis Data

In ICBayes: Bayesian Semiparametric Models for Interval-Censored Data

Description

A general interval-censored data set analyzed in Finkelstein and Wolfe (1985) and can be found in Sun (2006, page 7). Early breast cancer patients treated with radiotheraph alone or radiotherapy with adjuvent chemotherapy were examined periodically for breast retraction. Time was measured in months.

Usage

data(bcdata)

Format

A matrix with 96 rows and 4 columns. Each row (L, R, status, x1) corresponds to a patient in the study.

L

a numeric vector of left-points of observed time intervals

R

a numeric vector of right-points of observed time intervals

status

a vector of censorship indicators: 0=left-censored, 1=interval-censored, and 2=right-censored

x1

a vector of treatment indicators: 0=radiotherapy alone, 1=radiotherapy with adjuvent chemotherapy
