Birth Weight
In an investigation conducted by Secher et al., (1987), The birth weight (BW) in grams for 107 babies was ascertained. For all babies, both the abdominal (AD) and biparietal (BPD) diameters (in mm) were measured shortly before birth using ultrasound . The purpose of this study was to describe the relationship between birthweight and these two ultrasound measurements in order to establish a way to predict birthweight (or fetus weight). Variable list: bw: Birth weight of the baby in grams bpd: biparietal diameter (in mm), as determined by ultrasound ad: abdominal diameter (in mm), as determined by ultrasound id: identification of the mother (not needed)
