讨论了复生长曲线模型中尺度参数∑和位置参数ξ的检验问题.设原假设为①H1:∑=Ip(Ip为P阶单位阵);②H2:∑=Ip且ξ:0(0为q×m阶零矩阵);③H3:∑=σ2Ip(σ2〉0且未知).证明了当A为分块对角矩阵时,相应于备择假设Ai≠Hi(i=1,2,3)检验原假设Hi的似然比检验是无偏的.
The problems on hypothetical testing of scale and location parameter in a complex growth curve model are considered in this paper. Suppose the null hypotheses are as follows:①H1:∑=Ip(Ip is an identity matrix of order p);②H2:∑=Ip andξ:0(0 is a zero matrix of order q × m);③H3:∑=σ2Ip(σ2 is unknown positive number). It is derived that the likelihood tests of the null hypotheses Hi against above alternative hypotheses Ai≠Hi ( i = 1,2,3 ) are unbiased when ∑ is the form of block diagonal matrix in Section 2.
