Abstract:
|
We introduce a class of dynamic regression models designed to predict the future of growth curves based on their historical dynamics. This class of models incorporates both baseline and time-dependent covariates, start with simple regression models and build up to dynamic function-on-function regressions. Models from dynamic regression will be used to provide predictions of future observations and trajectories. Deviations from these predictions will be used for early detection of outlying observations or growth patterns. Methods are motivated by and applied to the CONTENT data set, a study that collected monthly child growth data on 197 children from birth until month 15.
