NeuDist (version 1.0.1)

relief: Relief Times of Patients Receiving an Analgesic

Description

This dataset contains the relief times (in hours) of 20 patients who received an analgesic. The data were originally presented by Gross and Clark (1976) in their work on survival distributions and reliability applications in biomedical sciences.

Usage

relief

Value

An object of class "numeric".

The vector consists of 20 observed relief times (in hours), each corresponding to a single patient who received an analgesic treatment. Each value represents the time elapsed from administration of the analgesic to the onset of pain relief. The dataset is commonly used in survival and reliability analysis to illustrate lifetime distributions, time-to-event modeling, and nonparametric estimation techniques.

Format

A numeric vector of length 20 containing relief times in hours.

Details

The dataset is frequently used in survival analysis to illustrate basic distributional behavior, reliability concepts, and nonparametric survival estimation. It serves as a benchmark example in many survival analysis textbooks.
