This data set consists of simulated measurements for an experiment conducted to evaluate the precision performance of measurement methods. On 20 days two separate runs with two replicates of the same sample are measured. Thus, factor 'day' is the top-level random factor (variance component), factor 'run' is nested within 'day'.
data.frame with 80 rows and 3 variables.
