emesis R Documentation
Motion sickness study.
Description
The data are from an experiment that investigated sickness from simulated sea motion. Subjects were put into a cabin mounted on a hydraulic piston and subjected to vertical motion for up to two hours. The length of time until each subject vomited was recorded. Note that some observations are right-censored.
Usage
emesis
Format
A data frame with 49 observations and three variables:
- minutes:
minutes until the subjecte vomited
- censored:
whether or not the time is censored (yes or no)
- motion:
simulated sea motion condition (a: frequency of 0.167 Hz and acceleration of 0.111g, b: frequency of 0.333Hz and acceleration of 0.222g)
Details
These data are from Burns (1984) but are also featured in Hand et al. (1994).
