| Abstract(in English) | Recently the wavelet analysis has been frequently used for not only image processing and signal processing but also time series analysis with high speed and accuracy requirements. In this article we apply a wavelet-based estimation method with the Haar-Fisz transform to estimation of non-homogeneous Poisson processes, and develop a novel software reliability assessment method. There are mainly two advantages for use of the wavelet-based estimation: (i) it does need no parametric assumptions on the software debugging scenario and (ii) the computational overhead arising in goodness-of-fit and prediction tests is rather small since the fitting procedure of data is quite easy and simple. Finally, we show through validation tests with real software fault data that our wavelet-based non-parametric estimation method can provide higher estimation performances than the conventional maximum likelihood estimation and the least squares estimation to estimate the number of detected software faults per testing date. |
