A New Reliability Model Based on Lindley Distribution with Application to Failure Data

Table 2

The model names and MVFs.

Model name	MVF
Goel–Okumoto (GO) model [4, 27]
Delayed S-shaped model [5, 28]
Inflection S-shaped model [6]
NHPP L model

where is the inflection factor; is the expected number of software faults to be eventually detected; is a constant of proportionality; and is the shape parameter for the Lindley distribution.
