Curve smoothing and transformations in the development of growth curves [PDF]
American Journal of Clinical Nutrition, 1999 Growth charts such as those published by the National Center for Health Statistics (NCHS) consist of a set of smoothed percentile curves showing the distribution of different aspects of body size for infants, children, and adolescents. The original NCHS growth charts are currently being revised to incorporate additional national data, to include growth

ON THE GROWTH OF ENTIRE CURVES
Mathematics of the USSR-Izvestiya, 1973In this paper we introduce a measure of deviation of an entire curve from a fixed vector. We establish sharp estimates and other relationships satisfied by this measure of deviation.

A Growth Curve Analysis for EDP Curves
Applied Statistics, 1983Summary: A class of exponentially damped polynomial (EDP) regression models was suggested by the author and \textit{J. A. Tredger} [ibid. 30, 147-152 (1981; Zbl 0464.62093)] to describe biological recovery data. Certain specifications are made here on the distribution of parameters over individuals which lead to exact expressions for the unconditional ...

On the Utility of Growth Curves
JAMA: The Journal of the American Medical Association, 1992In this issue ofThe JOURNAL, Yip et al 1 describe the changes that have taken place in a decade (1980 through 1989) in the birth weight and early childhood growth of children of low-income immigrant families from Southeast Asia. While Asian See also p 937. immigrant infants and young children showed a marked shift in growth status toward the reference

Clinical Obstetrics and Gynecology, 1997
Fetal growth is the principal issue in antenatal surveillance today. Its urgency is highlighted by audit data showing a powerful association between growth restriction and antepartum stillbirths. Customized growth charts optimize the assessment of fetal growth and birth weight by taking individual physiologic variables into account and by deriving an ...

Abstract This data set contains approximately 50 growth curves for a wide range of aluminum casting alloys at various temperatures. Growth curves are used to determine the dimensional changes that must be anticipated during service in applications where close dimensional tolerances are required.

A Probability Structure for Growth Curves
Biometrics, 1967SUMMARY A conditional probability density for body-weight of chickens is derived by making a priori assumptions about the probability densities of the descriptive parameters. This formulation incorporates the idea that animal to animal genetic differences, which dictate growth and hence the parameters in the describing function, can be realized as a ...

An extension of the growth curve model
Biometrika, 1988The growth curve model of \textit{R. F. Potthoff} and \textit{S. N. Roy}, ibid. 51, 313-326 (1964; Zbl 0138.143), is generalized in presenting the analysis of repeated measurements on experimental units grouped according to some experimental design. Especially the case is considered that the same number of observations at identical time points are made

Growth curves for preterm infants
Early Human Development, 2007The commonly used growth curves for preterm infants are four decades old and may not be suitable for the current population. Uncertainty exists regarding the most suitable curves for monitoring the growth of preterm infants. While intrauterine growth rate appears to be the ideal growth that needs to be attained by the preterm infants, it may not be ...

Standard growth curves for achondroplasia
The Journal of Pediatrics, 1978Standard growth curves for achondroplasia, the most common form of short-limbed dwarfism, have been constructed based on measurements of height, growth velocity, upper and lower segment, and head circumference in 400 achondroplastic dwarfs. These standard curves provide the basis to assess normal growth in these individuals, to aid in the determination
