galaxy: Galaxy velocities

In DPpackage: Bayesian Nonparametric Modeling in R

Description

This data set consider physical information on velocities (km/second) for 82 galaxies reported by Roeder (1990). These are drawn from six well-separated conic sections of the Corona Borealis region.

Usage

data(galaxy)

Format

A data frame with 82 observations on the following variable.

speed

a numeric vector giving the speed of galaxies ((km/second))
