Motivated by quantifying the monotonic relationship between gray matter (GM) volume and age in the older population, this study proposes a constrained nonparametric estimation and statistical inference for the monotone mean function of functional/longitudinal data. Under some mild conditions, we systematically investigate the asymptotic properties of the proposed estimators, using a general weighting scheme that includes an equal weight per observation (OBS) and an equal weight per subject (SUBJ) as special cases. Most existing methods without a structural constraint can handle sparse or dense data only. Thus, a subjective choice between the two types may lead to erroneous conclusions from statistical inferences. Our proposed 1 Statistica Sinica: Preprint doi:10.5705/ss.202018.0233
