Research ArticleOpen accessPhrase in the titleOn The Estimation of Survival Function and Parameter Exponential Life Time DistributionHadeel Salim Al-Kutubi, Noor Akma IbrahimProblem statement: The study and research of survival or reliability or life time belong to the same area of study but they may belong to a different area of application. In survival analysis one can use several life time distribution, exponential distribution with mean life time θ is one of them. To estimate this parameter and survival function we must … …Journal of Mathematics and Statistics, Vol. 5, Issue 2 · 30 Jun 2009 · 8,065 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIs Cancer Recurrence Postponed By a Treatment? A New Model AnswersRamalingam ShanmugamDuring a treatment period of a cancer patient, the medical team ponders over a question: Is patient’s cancer recurrence significantly postponed by the medication, even if the illness is not completely cured?

A scanning of the literature reveals that … …Current Research in Medicine, Vol. 4, Issue 1 · 26 Mar 2013 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSome Cubic Transmuted Exponentiated Pareto-1 DistributionHussein EledumIn this study, we introduce two new generalized versions of the Exponentiated Pareto-I distribution called (CTEP-I-G) and (CTEP-I-R). Statistical properties of the two distributions such as reliability function, hazard function, moments and moment generating function are studied. Models parameters are estimated by the maximum likelihood method. Finally, an application of CTEP-I-G and CTEP-I-R distributions to two real datasets and compared … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 14 Jul 2020 · 6,062 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBayes Estimation of the Lifetime Parameters for the Exponential DistributionAhmed A. Abu-Taleb, Mahmoud M. Smadi, Ameen J. AlawnehBayes estimation for the parameters of the lifetime distribution when both survival and censoring time are exponentially distributed were studied. The marginal posteriors, Bayes estimates and credible sets were derived using conjugate priors. …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 7,297 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAlzheimer’s Disease Prognosis is Captured by a Down-Upsized Incidence Poisson DistributionRamalingam ShanmugamAlzeimer disease is a daunting nightmare to both the medical and families of the patients. Tireless efforts are made by the medical researchers to treat Alzheimer’s patients. The Alzhiemer patients’ data provides clues about its prognosis and they can be identifies when the data are analyzed and understood correctly.

Research ArticleOpen accessIn the keywordsOdds to Quicken Reporting Already Delayed Cases: Acquired Immune Deficiency Syndrome Incidences are IllustratedRamalingam ShanmugamDelayed reporting in a medical system complicates efforts to estimate the number of cases that occurred in a time period. A case in point is the government’s difficulty to estimate the number of Acquired Immune Deficiency Syndrome (AIDS) cases. The reporting delays are not intentional but are ongoing due to changing Federal regulations or medical definitions of the case like … …International Journal of Research in Nursing, Vol. 4, Issue 1 · 1 Apr 2013 · 6,415 accessesView PDFCite
Literature ReviewOpen accessIn the abstractRumen Microbiota Mysteries: Nutrition, Function, and its Impact on Livestock ProductivityHamdi Mayulu, Marry ChristiyantoRuminants are important herbivores in the global food system, serving as primary producers of meat and milk. The productivity of these animals is influenced by the functionality of their digestive organs, namely rumen. The digestion, metabolism and nutrients absorption in the rumen epithelium enhance the host defende mechanisms mechanisms, promoting health and productivity in ruminants. Therefore, this review aimed to … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 4 Aug 2025 · 4,069 accessesView PDFCite
Case ReportOpen accessIn the abstractSurvival Following Severe Paraquat Poisoning a Case Study from the Andaman and Nicobar IslandsShiv Shankar Singh, Colin Sanchez, Prasan Kumar PandaParaquat poisoning continues to pose a significant public health challenge in the Andaman and Nicobar Islands, largely due to its alarmingly high mortality rate. In this report, we present the case of a 39-year-old male farmer who ingested 30 mL of paraquat with the intent of suicide.
