This file contains the data used for models of pup mass near parturition and contains the following columns: PartMass (kg), momAGE.c (maternal ages in years at weighing, centered using the mean), MidGain (kg/day for the first 20 days), LateGain (kg/day for days 20 to 35), Season (year of measurement), DTA (deviation from target age), Female (indicator variable for female), Btime.c (birthdate centered using the mean), Btime.c.sq (square of the previous term), momSPENO (unique identifier for mother), momAGE.c.sq (the square of the previous term), momAGE.log (the log transform of maternal age in years, made by subtracting the minimum age from each animal and adding a small constant), NPrevPup.c (the number of previous pups for each mother, scaled by the average number of pups at each age), PrevState (breeding state the previous season), PartMass.c (parturition mass centered according to the mean).
