cement: Hald's Cement Data

Description

Heat evolved in setting of cement, as a function of its chemical composition.

Usage

data(cement)
data(cement.miss)

Arguments

source

Woods, H., Steinour, H. H. and Starke, H. R. (1932) Effect of composition of Portland cement on heat evolved during hardening. Industrial Engineering and Chemistry, 24, 1207--1214.

Details

cement.miss is taken from an example in Little & Rubin's book on Statistical Analysis with Missing Data (2002), pp. 154, for demonstrating estimation of multivariate means and variances when the missing data pattern is monotone. These are indicated by NA in cement.miss. See the examples section of monomvn for a re-working of the example from the textbook.
