[,4]	age	age category Younger, Middle, Older.

Usage

data(fibroid)

Format

A data frame containing 240 observations on 9 variables.

Details

The response variable lfgr was calculated as the change in log fibroid volume, divided by the length of time between measurements. The growth rates were averaged to produce a single value for each fibroid, which was scaled to represent a 6-month percent change in volume.
