Hald data

Description

The following data relates to an engineering application that was interested in the effect of the cement composition on heat evolved during hardening (for more details, see Woods et al., 1932).

Usage

Hald

Format

A data frame with 13 observations on the following 5 variables.

y

Heat evolved per gram of cement (in calories)

x1

Amount of tricalcium aluminate

x2

Amount of tricalcium silicate

x3

Amount of tetracalcium alumino ferrite

x4

Amount of dicalcium silicate
