fat: Measurements of subcutaneous and visceral fat

In MethComp: Analysis of Agreement in Method Comparison Studies

Measurements of subcutaneous and visceral fat

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 )
