The Beta - Gompertz Distribution La Distribución Beta - Gompertz
In this paper, we introduce a new four-parameter generalized version of the Gompertz model which is called Beta-Gompertz (BG) distribution. It includes some well-known lifetime distributions such as beta-exponential and generalized Gompertz distributions as special sub-models. This new distribution is quite flexible and can be used effectively in modeling survival data and reliability problems....

متن کاملSoftware Reliability Estimation: Gompertz
oftware Reliability Growth Model is a mathematical model of how the software reliability improves as faults are detected and repaired. The performance of SRGM is judged by its ability to fit the software failure data. How good does a mathematical model fit to the data and reliability of software is presented in the current paper. The model under consideration is the, Gompertz model. MLE method ...
متن کاملThe Gompertz-Makeham distribution
This work is about the Gompertz-Makeham distribution. The distribution has been applied plenty of times. The properties of the Gompertz-Makeham distribution investigated in this work are unimodality of the Gompertz-Makeham distribution and relationship between the median value and the mean residual life time of the Gompertz-Makeham distribution. For most of the realistic set of parameter values...
متن کاملSince Since Kai
• The Perfect introduces a time interval: the “perfect time span” (PTS). • The Right Boundary (RB) of the PTS is set by Tense. • The Left Boundary (LB) of the PTS may be set by “perfect adverbials”. • The lower predicate (event) is predicated of the PTS, either directly or mediated by various devices, most notably operators associated with the Perfective or Imperfective. • When the predicate ha...
