In the process of software reliability demonstration testing there is a problem that traditional Bayesian method did not distinguish between historical information and experimental information.A hybrid Bayesian software reliability demonstration testing scheme is proposed.By introducing the concept of correlation coefficient

the correlation coefficients in hybrid Beta distribution are determined by subjective quantitative method

goodness of fit method

Kullback information method

Spearman correlation coefficient method and Kendall correlation coefficient method respectively.Finally

through experimental analysis

prove the feasibility of the 5 kinds of calculation method of correlation coefficient

and prove that differentiating the historical information and experimental information impacts acceptable quality level of software reliability demonstration testing.
