In the model under consideration for the circadian rhythm study there are three unknown physiological parameters involved: the level, the amplitude and the phase. This paper concerns the estimation of the group level, group amplitude and group phase of a certain group of individuals based on their time series data. Special attention is paid to the amplitude and phase parameters, and solutions are obtained for both the small-sample and the large-sample cases.
在用于昼夜节律研究的模型中，涉及三个未知的生理参数：水平、幅度和相位。本文关注基于某组个体的时间序列数据来估计该组个体的群体水平、群体幅度和群体相位。特别关注幅度和相位参数，并针对小样本和大样本情况都得出了解决方案。
