erpcp {sensitivitymv}

DNA Damage Among Welders

Description

Matched pairs of a welder and a control, matching for age and smoking. The values are DNA elution rates through polycarbonate filters with proteinase K (or erpcp). Data are originally from Werfel et al. (1998) and were used as an example in Rosenbaum (2007). Data are used to illustrate the senmv function in the sensitivitymv package.

Usage

data(erpcp)

Format

A data frame with 39 observations on the following 2 variables.

welder

erpcp value for the welder

control

erpcp value for the matched control

Source

Werfel et al. (1998).
