BiRepeated is a simulated data set with bi-Beta variables y1 and y2 on 200 independent cases. Both y1 and y2 are repeatedly measured at a given set of covariate values x = (0.1, 0.2, 0.3, 0.4, 0.5, 0.6). Joint zoib modeling is applied to examine the effect of x on y1 and y2 simultaneously.
AlcoholUse contains the county-level monthly alcohol use data from students in California in years 2008 to 2010. The data can be downloaded at http://www.kidsdata.org. The data has information on the percentage of public school students in grades 7, 9, and 11 in five buckets of days (0, 1-2, 3-9, 10-19, 20-30) in which they drank alcohol in the past 30 days. Since the percentages across the five days categories add up to 1 given a combination of County, Grade and Gender. Data points associated with 0 are completely redundant and are not in AlcoholUse. zoib is applied to examining whether the proportions of alcohocol use in the past month are different across gender, grade, days of drinking.
