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)
