R. Satya Prasad, Y. Sangeetha . SPC for Software Reliability using Inflection S-Shaped Model. International Journal of Computer Applications. 60, 2 ( December 2012), 22-27. DOI=10.5120/9664-3280
Traditional statistical analysis methods account for natural va-riation but require aggregation of measurements over time,which can delay decision making. Statistical process control (SPC) is a branch of statistics that combines rigorous time series analysis methods with graphical presentation of data,often yielding insights into the data more quickly and in a way more understandble to lay decision makers . SPC and its primary tool-the control chart-provide researchers and practitioners with a method of better understanding and communicating data from software reliability improvement process efforts . This paper provides an s-shaped software reliability growth model based on the Non-Homogenous Poisson Process (NHPP). The maximum likelihood approach is used to estimate the unknown parameters of the model.
