Enzyme: Enzyme activity data
Description
Three measurement of enzyme activity on 24 patients. The
measurements is of the enzymes sucrase and alkaline phosphatase. The
interest is to compare the 'homogenate' and 'pellet' methods.Format
A data frame with 72 observations on the following 3 variables.
meth- a factor with levels
SucHom SucPel
Alkphos, representing three different measurements, i.e.
homogenate and pellet values of sucrase, as well as homogenate values
of alkaline. item- a numeric vector, the person ID for the 24 patients
y- a numeric vector, the measurements on the enzyme activity.
