Simulated data set.


This data set was built using simulations of tables, then bills, then tipsbased on the bills. Large groups were assumed to only pay the gratuity,which is evident in the data. Tips were set to be plausible round values;they were often (but not always) rounded to dollars, quarters, etc.
