摘要
本文讨论带有多余参数,协方差具有Kala形式的广义线性模型.首先把这种形式的模型等价转化为带有多余参数,协方差形如V的线性模型,从而讨论其比较问题.然后,本文讨论不带有多余参数,但协方差形式为Kala形式的模型,并把其转化为通常的线性模型.依次化繁为简讨论模型比较问题.
This paper discussed the comparison of linear models with residual parameter and Kala-Form covariance matrices. We at first turned this kind of model into linear model with residual parameter and covariance matrix same as V, then discussed the comparison of linear model with Kala covariance matrix form without residual parameter, and turned this models into model (y, Xβ, V).
