I have a large data set of about 3000 cases. Each case is
getting multiple measurements at different gestational ages at which ultrasound
measures
are obtained on several fetal parameters. What is the best
way to obtain median values of these measures for the various weeks of
gestational age.?
The range of weeks is from 21 to 34 and each women has
a different number of measurements ranging from 1 to 4. Any advice would be appreciated.
If you can point me to a reference that would be useful.
