sitar: Super Imposition by Translation and Rotation Growth Curve
Analysis
Functions for fitting and plotting SITAR (Super
Imposition by Translation And Rotation) growth curve models. SITAR is
a shape-invariant model with a regression B-spline mean curve and
subject-specific random effects on both the measurement and age
scales. The model was first described by Lindstrom (1995)
<doi:10.1002/sim.4780141807> and developed as the SITAR method by Cole
et al (2010) <doi:10.1093/ije/dyq115>.
