Research ArticleOpen accessEvery word in the titleModeling of Some Dairy Performance Indices on Milk Somatic Cell Count in Holstein Dairy CowsAhmed Dawod, Sherif Shawky, Tamer M. Abdel-Hamid et al.This study was conducted to evaluate the direct and the indirect standardized effects of some dairy performance parameters (days dry, lactation length, parity, total milk yield and 305-day milk yield) on the milk Somatic Cell Count (SCC) of Holstein cows throughout modeling of these variables with the path analysis technique. During studying 617 Holstein cows were enrolled in the experiment … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 4 · 27 Oct 2019 · 7,239 accessesView PDFCite
Review ArticleOpen accessIn the keywordsReview of Zero-Inflated Models with Missing DataT. Martin Lukusa, Shen-Ming Lee, Chin-Shang LiThe literature of count regression models covers a large scope of studies and applications that implemented simple and standard models for count response variables by using Poisson regression models, binomial regression models, negative binomial regression models, geometric regression models, or generalized Poisson regression models. These regression models have received considerable attention in various situations. Nevertheless in many fields, the distribution … …Current Research in Biostatistics, Vol. 7, Issue 1 · 31 Oct 2017 · 14,410 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPOISSON-WEIGHTED EXPONENTIAL UNIVARIATE VERSION AND REGRESSION MODEL WITH APPLICATIONSHossein Zamani, Noriszura Ismail, Pouya FaroughiThis study introduces a new two-parameter mixed Poisson distribution, namely Poisson-Weighted Exponential (P-WE), which is obtained by mixing Poisson distribution with a new class of weighted exponential distribution. The new P-WE distribution provides a more flexible alternative for modelling over dispersed count data compared to Poisson distribution. The estimation procedures of P-WE distribution via method of moments and maximum likelihood … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 8 Mar 2014 · 7,345 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntervened 2-Tier Poisson Distribution for Understanding Hospital Site InfectivityR. ShanmugamProblem statement: Whether it is a surgical site or medical treatment at a hospital site, the nurses in particular and the entire medical team including surgeons/physicians in general undergo a risk of being infected ironically by the patients whom they intend to disinfect. There are 2-tiers of patients at the site. One type consists of patients who are internally and … …International Journal of Research in Nursing, Vol. 3, Issue 1 · 31 Mar 2012 · 6,927 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDoes Over or Under Dispersion in Inverse Binomial Data Suggest Anything? A Case in Point is the Waiting Time for Both Heart-Lung TransplantsRamalingam ShanmugamThe model is an abstraction of the reality. The selection of the usual inverse binomial as an underlying model for the number of patients waiting in months for heart and lung transplant is questionable because the data exhibit not the required balance between the dispersion and its functional equivalent in terms of the mean but rather an over or under … …Current Research in Biostatistics, Vol. 3, Issue 2 · 29 Jan 2014 · 6,891 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. The data analysis is a first step in the path to … …Current Research in Medicine, Vol. 4, Issue 2 · 4 Sep 2013 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Phenotypic Plasticity in Dairy Production Traits of Toggenburg Goat Genotypes Across South African Agro-ecological ZonesMatshebuka Tshepho, Obert Tada, Louis Thobela TyasiThe study evaluated phenotypic plasticity (PP) in reproductive and milk production traits of Toggenburg (TOG) goat genotypes across five South African agro-ecological zones (AEZ) using a longitudinal observational design. Data from 2,417 does representing five genotypes (Founders, CP, Appendix A, Appendix B, and StudBook Proper) were sourced from the Milch Breeders Society of South Africa LOGIX database. Descriptive statistics and … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 25 Nov 2025 · 2,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractHaemato-Biochemical Indices of Red Sokoto Goats Fed Various Levels of Earthworm Meal-Based DietsMoshood Adewale Belewu, Ling Shing Wong et al.Blood is essential to life and it is vital for the transportation of oxygen from the lungs to every cell of the body for metabolism purposes. Hence, blood samples were collected from thirty (30) healthy Red Sokoto goats fed an earthworm meal-based diet with ten goats per treatment constituting a replicate in a Completely Randomized design model to evaluate the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 3 Dec 2024 · 4,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Selenium Supplementation on Secretion of Reproductive Hormones and Immune Response to Trichostrongylidae Nematodes Infestation in Zulu Sheep Ewes During Oestrous CycleNoxolo Winile Nkunzi, Fhulufhelo V Ramukhithi, Ismaila Muritala et al.The growing resistance of nematodes to anthelmintics has prompted research into alternative control strategies, including nutritional supplementation with micronutrients such as Selenium (Se). Research focusing on the use of mineral supplementation would not only contribute to improvement of animal performance but also to acquaint stakeholders with alternative immune boosting strategies in livestock. Thus, this research assessed how immune response and … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 27 Oct 2026 · 51 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Comparative Effectiveness of Ensemble CatBoost Versus XGBoost Models in Predicting Heart Disease OutcomesManivannan D., G. Gifta Jerith, G. Chandra Sekhar et al.Cardiovascular Diseases (CVDs) are a common form of heart disease that remains a significant global cause of mortality, responsible for more than 30% of all fatalities. Without intervention, the global fatality count is projected to reach 22 million by 2030. Arterial plaque buildup may impede blood flow, potentially causing heart attacks or strokes. A combination of risk causes, including lack … …Journal of Computer Science, Vol. 22, Issue 4 · 4 May 2026 · 1,552 accessesView PDFCite
