The often used data set for interval-censored data, described and given in full in Finkelstein and Wolfe (1985). It involves 94 breast cancer patients who were randomized to either radiation therapy with chemotherapy or radiation therapy alone. The outcome is time until the onset of breast retraction which is interval-censored between the last clinic visit before the event was observed and the first visit when the event was observed. Patients without breast retraction were right-censored.
A data frame with 94 observations and 3 variables:
left end point of the breast retraction interval
right end point of the breast retraction interval
type of treatment received
