Abstract: Based on Bootstrap estimate method being introduced into
the reliability statistical analysis, the Bootstrap interval estimate
method of the reliability parameter and characteristic value is
proposed. At the same time, by correcting the bias of the Bootstrap
estimate value, the problem, i.e. Bootstrap interval estimate precision
under the condition of small sample, is also solved, and the confidence
interval estimate value of the reliability parameter for one type of
aerospace electrical connector is obtained. From the result of
statistical simulation computation, the estimate precision of
reliability confidence interval is satisfied with the demand of
confidence degree, where the bias is corrected by adopting median value
technique.
