HUMAN GROWTH CURVE

Latent Growth Curve Modeling

A fundamental observation in the social and behavioral sciences is that people change over time, but not necessarily in the same way or at the same rate. For example, verbal ability increases steadily throughout the elementary school years, but it does not increase at the same rate for all students. There are individual differences in the rate and direction of change in many contexts, and these...

doi: 10.3969/j.issn.1002-0829.2012.06.009 Division of Biostatistics, Thomas Jefferson University, Philadelphia, Pennsylvania, USA *Correspondence: [email protected] Psychiatric studies often collect longitudinal data to characterize the natural history of disease in a cohort or to evaluate the effect of behavioral or pharmaceutical interventions. For example, in a recent partially ra...

Latent Growth Curve Analysis

Learning and development are ubiquitous. When new skills are acquired, when attitudes and interests develop, people change. Measuring change demands a longitudinal perspective, with multiple waves of data collected on representative people at sensibly spaced intervals. Multi-wave data is usually analyzed by individual growth modeling using a multilevel model for change (Singer & Willett, 2003)....

Fetal Growth Curve in Neonates in Alzahra Hospital in Rasht

ABSTRACT Evaluation of intrauterine growth and determination of at risk neonates was done by weight criteria for each pregnancy age. This criteria in different populations is not similar. Main objective of this study was determination of intrauterine growth pattern in this region. Weights of 2380 term neonates and 788 preterm neonates that had a definite LMP and were born at Alzahra hospital i...
