In this article, by two kinds of methods we convert step-stress data into constantALT data. Then according to the result of constant ALT, we give out empiricaldistribution estimation ,twice restricted maximum likelihood estimation,twice Bayesestimationand and twice linear estimation of production in the Stress level s_k.
