查询词典 empirical

At the beginning, an engineering method called semi-empirical reliability estimation method is introduced. Then, a detailed introduction of the bootstrap method, which has been widely applied to small sample reliability assessing since it was proposed in 1979, is made immediately. At last, a promoted virtual sample expanding method, that the reliability test sample size is expanded from 2-3 to 10, is proposed on the basis of predecessors research results. And the new method associated with bootstrap method is used to assess the test life lower limit in the case of logarithmic normal distribution.
