METHOD AND PROGRAM FOR PREDICTING SOFTWARE RELIABILITY, COMPUTER READABLE RECORDING MEDIUM RECORDING THE PROGRAM, AND DEVICE FOR PREDICTING SOFTWARE RELIABILITY

摘要

PROBLEM TO BE SOLVED: To provide method and program for predicting software reliability, a computer readable recording medium recording the predicting program, and a software reliability predicting device allowing accurate planning of a test process by estimating an upper limit of an estimated value of the number of potential bugs existing in software just after starting the test and thus estimating the test period somewhat long. SOLUTION: In regression analysis for estimating a parameter of a software reliability growth model, a parameter is estimated using software reliability growth model and equation in a continuous limit and a differential equation that has a matched exact solution and is equivalent to projection conversion and using a property related to an obtainable compound ratio value of the projection conversion.
