Bandla Srinivasa Rao, R. Satya Prasad, K. Ramchand H.rao . A Comparative Study of Assessing Software Reliability using SPC: An MMLE Approach. International Journal of Computer Applications. 50, 19 ( July 2012), 23-27. DOI=10.5120/7911-1159
The Modified Maximum Likelihood Estimation (MMLE) of the parameters of Exponential and Half Logistic distributions are considered and compared. An analytical approximation is used instead of linear approximation for a function which appears in Maximum Likelihood equation. These estimates are shown to perform better, in the sense of simplicity of calculation than the one based on linear approximation for the same function. In this paper we identified the MMLE method of estimations and associated results using Half Logistic Distribution and Exponential Distribution are similar. These estimates are used in SPC to find the control limits to predict the software reliability. A comparison of software reliability using Statistical Process Control for a small sample is also presented
