摘要
对于两个生长曲线模型ｇ１＝Ｇ（Ｘ１ＢＺ１，Ｖ１，Ｉｎ１）和ｇ２＝Ｇ（Ｘ２ＢＺ２，Ｖ２，Ｉｎ２），其中Ｖ１和Ｖ２是已知的对称非负定矩阵，本文在可估子空间Ｄ上对它们进行了比较，得到了ｇ１ ｇ２（Ｄ）的几个充要条件。
For two growth curve models g1 = G (X1BZ1, V1, In1 ) and g2 = G(X2BZ2, V2,In2 ), where V1 and V2 are known symmetric nonnegative definite matrices, we mfore a com-parison between them in estimable subspace D and obtain several necessary and sufficientconditions of g1 g2(D).
