DCLHb: DCLHb dataset

In Agreement: Statistical Tools for Measuring Agreement

Description

DCLHb is a treatment solution contain oxygen carrying hemoglobin. The DCLHb level is routinely measured by the Sigma method, and the simpler HemoCue method was modified to reproduce the DCLHb values of the Sigma method. The DCLHb values of each sample were measured by both methods twice.

Usage

data(DCLHb)

Format

A data frame with 299 observations on 4 variables, 2 variables for Sigma method and 2 variables for HemoCue method.

Examples

data(DCLHb);
HemocueAve <- apply(DCLHb[,c("HEMOCUE1","HEMOCUE2")],1,mean);
SigmaAve <- apply(DCLHb[,c("SIGMA1","SIGMA2")],1,mean);
