Abstract
Cheng and Wei (2000) proposed a simple inference procedure to estimate regression coefficients of a semiparametric model for repeated measurements observed at irregularly spaced time points. This article provides an inference procedure to estimate baseline mean functions. Based on this procedure, a way to estimate mean functions of a subject with specific covariate information is provided. A way to construct point-wise confidence bands is also proposed. Our proposal is illustrated with a dataset from a clinical trial.
