REFINEMENT OF THE LINEAR ESTIMATION FOR AN ACCELERATED LIFE TEST

Zhang Zhihua (Navy Engineering Institute, Wuhan 430033) Mao Shisong (East China Normal University, Shanghai 200062)  
It is important to estimate two coefficients a and b of the acceleration equation in an accelerated life test. This paper gives two new linear unbiased estimations (BGLUE, RGLUE) of a and b which are much improved in comparison with the general weighted least square estimation in . By BGLUE and RGLUE two linear invariant estimations BGLIE and RGLIE have been composed better than those (GLUE) given in .
