Another simple use of the models would be in a sample survey, for example to find out levels of depression in primary care. A random sample of practices is chosen and within them a random sample of patients. The effect of being cared for by a particular practice on an individual is not of prime interest. If we repeat the study we would have a different set of practices. However, the variation induced on the estimate of the proportion of depressed patients by different practices is of interest, as it will affect the confidence interval (CI). Thus, we need to allow for between-practice variation in our overall estimate.
