Simulated dataset
We generated a data set with 20,000 individuals, which was considered as a target population. In this data set, variable From this target population, we randomly drew 3000 samples. Each sample contained 200 observations (i.e. ‘individuals’) and were randomly drawn from the target population. Also, we drew another 3000 samples with 100 individuals per sample in a similar fashion, in order to further validate our results given a different sample size.
