【 摘 要 】

People are interested in monitoring growth in many fields. Growth charts provide an approach for doing this, illustrating how the distribution of a growth measurement changes according to some time covariate, for a particular population. The general form of a growth chart is a series of smooth centile curves showing how selected centiles of the growth measurement change when plotted against the time covariate.These curves are based on a representative sample from a reference population. Different modelling approaches are available for producing such growth charts, including the LMS method and quantile regression approaches. These approaches are explored in this thesis using data from the Growth and Development Study data, which allows construction of gender-specific weight growth charts for full-term infants.
