For this purpose, a residual process is defined by subtracting the predicted from the observed response functions. Graphical methods based on the functional principal component scores of observed and fitted functions can be used to complement more formal tests. For the case of a univariate covariate, a randomization test is proposed based on these scores to examine if the residual process depends on the covariate. These methods are illustrated with real data applications. --
