Data of sitting distolic blood pressure (SiDBP)
These data have been simulated with respect to the descriptive statistics given in the bifactorial hypertension clinical trial reported by Hung (2000). Various distributional properties have been realized for normal and skewed cases with equal variances as well as with linearly increasing variances. The latter means that the coefficient of variation is held constant over the treatment groups. The group defining variable is named cb in the data set. It has got the levels (0,0), (1,0), ..., (2,3) according to the respective dose combinations. The data vectors with the different distributional properties are ynrmhom, ynrmhet, yloghom and yloghet.
