A Growth Curve Analysis for EDP Curves
研究了Crowder和Tredger提出的指数阻尼多项式回归模型，通过参数分布假设推导出非线性响应曲线的无条件均值和方差，并将分析扩展到多处理组设计。
A class of exponentially damped polynomial (EDP) regression models was suggested by Crowder and Tredger (1981) 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 mean and variance of the nonlinear response curve. The analysis is also extended to more general designs than a single treatment group.
