airspeed: Air speed experiment data

In lmreg: Data and Functions Used in Linear Models and Regression with R: An Integrated Approach

Description

Air speed data, which is part of a larger data set from a designed experiment (Wilkie, 1962).

Usage

data(airspeed)

Format

A data frame with 18 observations on the following 3 variables.

Posmaxspeed

The position of highest speed of air blown down the space between a roughened rod and a smoothed pipe surrounding it. The position is defined as the distance (in inches) from the center of the rod, in excess of 1.4 inches

Reynolds

Reynolds number of air flow (dimensionless)

Ribht

Height of ribs on the roughened rod (in inches)
