In this paper we describe some mathematical and statistical models for dealing with changes over age. We concentrate specifically on the use of a structural equation modeling (SEM) approach (using computer programs like LISREL) to deal with issues of: (1) group differences in regression parameters, (2) differences in longitudinal and cross-sectional results, (3) differences due to longitudinal attrition, and (4) mixtures of these problems. To illustrate these ideas we use data from a previous study of hypertension and intellectual abilities (from Schultz, Elias, Robbins, Streeten, and Blakeman, 1986).
在本文中，我们描述了一些用于处理随年龄变化的数学和统计模型。我们特别专注于使用结构方程建模（SEM）方法（使用诸如LISREL之类的计算机程序）来处理以下问题：（1）回归参数中的组间差异；（2）纵向和横断面结果的差异；（3）纵向损耗导致的差异；以及（4）这些问题的混合情况。为了说明这些观点，我们使用了先前一项关于高血压与智力能力研究的数据（来自舒尔茨、埃利亚斯、罗宾斯、斯特里滕和布莱克曼，1986年）。
