Research Of Software Reliability Estimation Method Based on Bayes Theory

摘要

By the Bayesian method, a formalistic description is presented based on the random testing procedure of input area, a Software Reliability Estimation Method is bringed forward that make use of size of the random testing muster and the random right times, It will help to define the prior information needed by the Bayesian method. According to the general information, the prior information and the testing information, the post probability density function can be constructed, that can be used to calculate the correctness probability of a program. The selection method commendably solves the problem of the parameter estimate about the prior probability density function of the disabled behavior of software. When the method compares with Software Reliability Estimation Method Based on time area it has briefness character, sufficient academic gist, easy intellect, and the data collectes easily etc.
