Note 1: There are two data sets recorded here. The DEA data are coded as 1 and the U.S. Customs Service data are recorded as 2. There are 40 observations included in both data sets, and they are coded as 12. The DEA data consist of 141 observations and the U.S. Customs Service data consist of 117 observations. Note 2: In general, an asterisk (*) denotes that the observation was not recorded. In the case of 18 of the gross weight values, an asterisk shows that each of those recorded values were less than or equal to the corresponding recorded net weight value, which is impossible. Note 3: For the gender variable, a female is coded as 0 and a male is coded as 1. Note 4: The age variable is given in years. It was calculated by subtracting date of birth from date of arrest.
