Explain human height growth curves, Advanced Statistics

Assignment Help:

Human height growth curves: The growth of human height is, in common, remarkably regular, apart from the pubertal growth spurt. The satisfactory longitudinal development curve is extremely useful as it enables long series of the measurements to be replaced by a few parameters, and may permit early detection and treatment of the growth abnormalities. Many such curves have been proposed, of which possibly the most successful is the the below written five-parameter curve

 where
 t = time (prenatal age measured from day of birth),
 X = height reached at the age t,
A = is the adult height,
B = height reached by the child at age E,
 C =a ?rst time-scale factor in units of the inverse time,
 D= a second time-scale factor in units of the inverse time,
 E = approximate time at which pubertal growth spurt happens.
