The admissibility of non-homogeneous quadratic form estimateofvariance on the growth curve model was studied under quadratic loss function.

Suppose the estimated duration of a task is 3 months, and the varianceof the estimate is 1 month.
假设估算的任务持续时间是 3 个月，并且估计的方差是 1 个月。

In this case optimally weighted LS estimate is not a linear estimateof a parameter given input and observation anymore and can not be compared with linear minimum varianceestimate.
