Stability moisture data of three batches

Description

A data set containing the moisture stability data (% (w/w)) of three batches of a drug product obtained over a 24 months period. A total of n = 33 independent measurements are available (corresponding to data shown in Table XIII in LeBlond et al. (2011)).
