  • 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 ...
