本文提出了一种在基线时间趋势未知的情况下估计生长曲线模型回归系数的方法。该方法的概念类似于考克斯比例风险模型。没有特定的形状被假定为基线时间趋势，或者，也可以假定它们是非参数估计的。由于基线趋势的这些讨厌的参数，我们不必注意对这些形状进行建模。除了简单的建模基线曲线，我们还可以通过使用回归系数估计后的残差来非参数化地描述基线趋势。
SYNOPTIC ABSTRACTThis article presents a method for estimating the regression coefficients for a growth curve model when the time trend of the baseline has not been specified. The concept of this method is similar to that of the Cox proportional hazard model. No particular shape is assumed for the baseline time trends, or, alternatively, it can be assumed that they are estimated nonparametrically. Because of these nuisance parameters for the baseline trends, we do not have to pay attention to model those shapes. In addition to the simplicity of modeling baseline curves, we can also nonparametrically describe the baseline trends by using the residuals after the regression coefficients have been estimated.
