The associations between the random effects are shown in the scatterplot above right , where timing is negatively correlated with intensity, but size is uncorrelated with timing and intensity. Her adjusted curve is the upper red curve. For the tall girl id in blue , her mean height is estimated as To illustrate this we use the berkeley dataset to explore the growth of height in girls during puberty. Patterns of growth Looking at the individiual curves, some girls are consistently taller than average and others consistently shorter. Mean curve The SITAR mean growth curve is estimated by taking the adjusted curves above right and fitting a natural cubic spline through them below left. Note that the two adjusted curves are very close to the mean curve, showing how effectively SITAR superimposes the curves. SITAR is a form of growth curve analysis that models the biology of growth.
