This paper is concerned with a problem of testing hypotheses about the mixing proportion [theta] of a mixture of two known distributions. A locally most powerful unbiased (LMPU) test for testing the hypotheses H0: [theta] = [theta]0 vs. H1: [theta] [not equal to] [theta]0 (0 [theta]0 1) is...

This paper presents simulation results on the robustness of normal parametric inference in non-linear mixed models. A linearization approach to inference is compared with two two-stage methods (standard two-stage, STS, and global two-stage, GTS). When the assumptions of normality of the...
