Tribolium Larval Mass Data

The file gives mass measurements for individuals who are listed in rows. The first three columns list identifying information for each larva; the first column gives the ID number, the second gives the sire number, and the third gives the dam number. The fourth column gives the hatch date, from which each 'age' is measured. From here, each data entry takes three columns: one for date of measurement, one for days since hatch (or, age at measurement), and one for the actual mass measurement (which is in grams). The numbers following the headings in this column represent the number of each measurement (i.e. 'mass5' indicates the fifth mass measure). Data concerning the pupal stage begin at the 44th column. The first three columns are the date of pupation, pupation age, and pupal mass. The 47th column indicates the sex of the individual, with 1 representing a male and 0 representing a female. The last two columns indicate the date and age of eclosion to the adult stage, respectively. Any blank entries represent a lack of data points either for that measurement or for that identifying information.

本数据集提供了按行排布的受试个体体重测量数据。前三列为每只幼虫的标识信息：第一列为个体编号ID，第二列为父本编号，第三列为母本编号。第四列为孵化日期，所有个体的日龄均以此为起始点进行计算。后续每组测量数据占用三列，依次为测量日期、孵化后天数（即测量时的个体日龄），以及实际体重测量值（单位：克）。列标题后的数字代表该体重测量的次数，例如“mass5”即表示第五次体重测量。蛹期相关数据始于第44列，其前三列依次为化蛹日期、化蛹时的日龄以及蛹体重。第47列为个体性别标识，其中1代表雄性个体，0代表雌性个体。数据集最后两列分别对应成虫羽化日期及羽化时的日龄。所有空白条目均代表对应测量项或标识信息缺失有效数据。
