Quantiles based Neighborhood Method of Classification

Sampath, S.; Suresh, S. (2019-05-01)

Classification of objects is an important problem that has received the attention of several researchers in Data Mining. Necessity for classification of an object into one of the predefined classes arises in several domains ...
A Queuing Model for Determining the Optimal-Mix of ATMs AND POS terminals in a Commercial Bank: An Implication to the Cash-less Policy in Nigeria

Onuche, Agada P.; Korve, Kenneth N.; Kazeem, Raifu (2018-05)

In the bid to actualizing the cashless policy in Nigeria, this study criticized the multiplication of Automated Teller machines (ATM) in commercial banks as recommended by most authors and emphasized the role of the Point ...
A Queuing Model for Hospital Bed Occupancy Management: A Case Study

Kembe, M.M.; Agada, P.O.; Owuna, D. (2014)

The quality of Medical Service in the Orthopaedic clinic of the NKST Rehabilitation Hospital Mkar is constantly threatened by the inadequacy of hospital beds across wards. This is due to the high influx of patients needing ...
Siginificance Test Based on Log-Logistic Distribution

Kantam, R. R. L.; SriRam, B.; Suhasini, A. (2015)

This paper deals with the log-logistic distribution (β = 3) as a life time model. Moments of order statistics and an ordered sample are used to define a test statistic for the null hypothesis that the considered random ...
A Simulation Study of the Negative Effects of the Single Block Appointment System in Specialist Outpatient Clinics of a Tertiary Healthcare Institution

Agada, P.Onuche; Kenneth, N. Korve (2015)

This paper is concerned with the investigation of the negative effects of the Single Block Appointment System via a simulation study of queues in selected specialist outpatient clinics of a tertiary healthcare Institution. ...
Simulation-Cum-Regression (SICURE) Method of Estimation for the Small Domains

Tikkiwal, G.C.; Rai, Piyush Kant; Goyal, Teena (2020-05-01)

When we talk about small domain problems, the sample regression method is extensively used to build up Small Area Statistics. It is brought out that this method is a special case of the Theory of Successive Sampling. This ...
Smaller Balanced Sampling Plans Excluding Adjacent Units for One Dimensional Population

Kumar, Rajeev; Parsad, Rajender; Mandal, B. N. (2016)

Balanced sampling plans excluding adjacent units are used for selecting samples from naturally ordered populations where nearer units provide similar measurements. In this article, we present several new balanced sampling ...
A Solution of the Two-Sample Problem

Tsakok, AD (2014)

The Tsakok test of fit is used to obtain an exact interval estimate of distributions and achieves exact two-sample tests, UMPU in a class of two-sided alternatives and not conditional on marginal totals. Com¬parisons and ...
Some Bivariate Gamma Distributions

AlAhmad, Rami (2016)

In this paper, we find integral presentations of incomplete gamma functions. Using these results we construct bivariate gamma distributions and prove some properties of such distributions.
Some Characterization of Continuous Distributions Based on Order Statistics

Athar, Haseeb; Athar, Zuber (2015)

A family of continuous probability distributions have been characterized through conditional expectation of power of difference of two order statistics, conditioned on a pair of non-adjacent order statistics. The ...
Some Characterizations of Chaudhry and Zubair’s Extended Generalized Inverse Gaussian Distribution

Ahsanullah, M.; Shakil, M. (2020-05-01)

The objective of this paper is to characterize Chaudhry and Zubair’s extended generalized inverse Gaussian distribution [11] [Chaudhry, M. A., Zubair, S. M.: On A Class of Incomplete Gamma Functions, with Applications. ...
Some Univariate Continuous Frailty Models

Parekh, S. G.; Patel, S. R. (2018-05)

In this paper we have considered some univariate distributions and their frailty models, such as Gamma frailty model, Weibull frailty model, generalized exponential frailty model, Exponential power distribution as frailty ...
Statistical Issues in Small and Large Sample: Need of Optimum Upper Bound for the Sample Size

Chandrasekharan, Subramanian; Sreedharan, Jayadevan; Gopakumar, Aji (2019-11-01)

As fewer samples are meaningless and lead to fallacious conclusions, researchers are used to calculate minimum sample size before the conduct of any study. Although the larger samples can yield more accurate results, an ...
A Stochastic Model for The Inventory Management of Antiretroviral Drugs: A Case Study

AGADA, P. O.; UGER, K.H. (2017-11)

The Anti Retroviral Treatment (ART) programme of Our Lady of Apostle Hospital Akwanga, Nigeria is faced with uncertain demands for antiretroviral (ARV) drugs and as a result of these, the management encounter stock-outs ...
A Study on Block Design with Censored Data

Sarmah, Sanhita; Gogoi, Bipin (2015)

The analysis of data from block designs arises in different fields. Various parametric and nonparametric procedures are available for analysis of such data. But analysis of such design with censored data has not been as ...
Summarizing Test Grades Using Descriptive Statistical Tools

Al-Saleh, Mohammad Fraiwan (2019-11-01)

In this paper, several Educational Statistical Tools for summarizing a test marks are discussed. The mean, variance, 5- number summary, Difficulty index and Discrimination index are discussed in details. The tools are ...
Test for Accuracy of Ranking in Moving Extreme Ranked Set Sampling

Al-Saleh, Mohammad Fraiwan; Ababneh, Asma (2015)

Moving Extreme Ranked Set Sampling (MERSS) is a variation of Ranked Set Sampling (RSS) that simplifies the technique and makes it more applicable. In MERSS, the judgment maximum of random samples of sizes 1, 2,…, are taken ...
Testing the Population Kurtosis Parameter: An Empirical Study with Applications

Guo, Yawen; Kibria, B. M. Golam (2017-05)

The purpose of this paper is to propose some test statistics for testing the kurtosis parameter of a distribution. Since a theoretical comparison among the test statistics is not possible, a simulation study has been ...
Time Control Chart – Log Logistic Distribution

B., SriRam; A., Suhasini; R.R.L., Kantam (2019-05-01)

The time to failure of a product is considered as a quality characteristic of following Log-Logistic distribution (β = 3). Control limits are evaluated for the time to failure. Life time data are compared with the control ...
Using Rank of the Auxiliary Variable in Estimating Variance of the Stratified Sample Mean

Shabbir, Javid; Gupta, Sat (2019-11-01)

We propose a generalized class of estimators for finite population variance using the auxiliary variable as well as rank of the auxiliary variable in stratified sampling. We identify many estimators as special cases of ...
