We study the admissibility of the quadratic estimate for error variance in two classes of growth curve model.
所以她应该考虑所有误差曲线，i.e，她不得不处理很多二次方程函数使新误差定义代表总误差。
So she should take all error curves into account, i. e., she has to deal with many quadric functions and make a new error definition to represent the total error.
