We assume that repeated measurements are taken on each of several subjects that are randomly sampled from some population. The observations on a particular subject are expressed as the sum of an average curve for the population and a deviation of the subject’s curve from the average plus independent errors. Both curves are modeled nonparametrically as splines. We use roughness penalties on the splines, which is equivalent to assuming a linear mixed model. Within this linear mixed model, we… CONTINUE READING
