fat: Measurements of subcutaneous and visceral fat

In MethComp: Analysis of Agreement in Method Comparison Studies

Description

43 persons had Subcutaneous and Visceral fat thickness measured at Steno Diabetes Center in 2006 by two observers; all measurements were done three times. The interest is to compare the measurements by the two observers. Persons are items, observers are methods, the three replicates are exchangeable within (person,observer)=(item,method)

Format

A data frame with 258 observations on the following 6 variables.

Id

Person id.

Obs

Observers, a factor with levels KL and SL.

Rep

Replicate — exchangeable within person and observer.

Sub

Subcutaneous fat measured in cm.

Vic

Visceral fat measured in cm.

Examples

data(fat)
str(fat)
vic <- Meth( fat, meth=2, item=1, repl="Rep", y="Vic" )
str(vic)
BA.est( vic, linked=FALSE )
