Analysis of Repeated Measures Designs with Changing Covariates
重新审视Patel（1986）提出的模型，将其表示为似不相关回归以简化估计，并讨论一般线性假设下的约束估计及两阶段过程。
A model proposed by Patel (1986) is re-examined. It is shown that the model can be written as seemingly unrelated regressions and estimation can be carried out simply. Estimation under constraints given by the general linear hypothesis is also discussed and a two-stage procedure proposed. Connexions with seemingly unrelated regressions with constraints between the regression parameters and the sum of profiles model of Verbyla & Venables (1988) are also given.
