Mathematical Analysis of prey-predator model
Abstract: In this paper we considered a model with a prey and predator involve holling type -II functional response. The predator species is not only dependent on prey species but also have alternative food source. The mathematical model is characterized by the couple of differential equations. The model is well posed and possess positive solutions. The system is bounded and shows the property of permeance. The possible equilibrium points are identified. …

Testing for equalities of several multinomial distributions
Abstract: In this article we have studied the testing of parameters of several multinomial distributions. The necessary conditional distribution of complete sufficient statistic of the parameter of interest is obtained by conditioning the complete sufficient statistics of nuisance parameter to be held fixed .Using this conditional distribution we have derived uniformly most powerful unbiased (UMPU) test for testing the hypothesis (i)Equality of two independent multinomial distributions and (ii) testing one of …

A statistical analysis of Indian National Florence Nightingale Nurses Awards, 1973-2023
Abstract: This study is an attempt to analyses 614 National Florence Nightingale Nurses Awards for the period of 1973-2023. It analyses year-and gender-wise number of awardees or awards including posthumous and off-service awards. This study has also been able to find number of recipients or awards according to state, category and affiliation. The result shows that the number of awards has gradually increased from the beginning and mostly given from 2008 …

Grey relational fractional programming and cross-evaluating method for multi-attribute decision making problem in spherical fuzzy setting
Abstract: To apply the spherical fuzzy sets(SFSs) for multiple attribute decision making (MCDM) problems have the more realistic significance, because of the assessment data specified by experts are mostly fuzzy and uncertain, the uncertainty and vagueness, ambiguity and subjectivity of the information in an intricate decision making environment, In this paper, a method to acquire attribute weights of interval number form by using the maximization method of the grey relational relative …
