2. Software Reliability Growth Models (SRGMs)
• SRGMs are useful for assessing software reliability (quality), Information is
useful for:
– Assessing the release readiness; and
– Testing resource allocation decisions
• Two of the widely known and recommended techniques for parameter
estimation are Maximum Likelihood Estimation (MLE) and method of least
squares (NLR)
• We compare between the two estimation procedures for their usability and
applicability in context of SRGMs
