The cost of medical resources used is often recorded for each patient in clinical studies in order to inform decision-making. Although cost data are generally skewed to the right, interest is in making inferences about the population mean cost.

This paper describes possible parametric models for analysing cost data. Four example data… CONTINUE READING
