Abrasion Index for the Tire Tread

Description

To understand the relationship between the abrasion index for the tire tread, the output y, as a linear function of the hydrated silica level x1, silane coupling agent level x2 and the sulfur level x3, Derringer and Suich (1980) collected data on 14 observation points.

Usage

data("abrasion_index")

Format

A data frame with 14 observations on the following 4 variables.

x1

hydrated silica level

x2

silane coupling agent level

x3

sulfur level

y

abrasion index for the tire tread

Examples

data(abrasion_index)
ailm <- lm(y~x1+x2+x3,data=abrasion_index)
