A Model for the Sequence of Positive and Negative Maximum Air temperature Anomaly in Port Harcourt, Nigeria

AGADA, P.O.; AGADA, I.O.; ANNONGU, W.D. (2016)

This work employ the Markov Chain model in modeling the sequence of positive and negative maximum air temperature anomaly in order to provide information for weather or climate assessment of the city of Port Harcourt, ...
Economic Reliability Test Plan under Hybrid Exponential Distribution

Sampath, S.; Lalitha, S. M. (2016)

The question of developing Economic Reliability Test Plan is considered in this paper assuming product lifetime follows Hybrid Exponential Distribution. Economic Reliability Test Plans determine the time to terminate the ...
New Classes of Univariate Continuous Exponential Power Series Distributions

Ahsanullah, M.; Hamedani, G. G.; Shakil, M.; Kibria, , B.M. Golam; George, F. (2016)

Recently, many researchers have developed various classes of continuous probability distributions which can be generated via the generalized Pearson differential equation and other techniques. In this paper, motivated by ...
New Nonparametric Ranked Set Sampling

Bhoj , Dinesh S. (2016)

A new nonparametric ranked set sampling (NNRSS) procedure is proposed to estimate the mean of a population. The estimator based on NNRSS is compared with the estimators based on ranked set sampling (RSS) and median ranked ...
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.
On Bayesian Estimation in Group Screening Designs without Errors in Decisions

Muhua, G. O.; Ottieno, J. A. M. (2016)

Group screening or testing has long been recognized as a safe and sensible alternative to one-at-a-time testing in applications wherein the prevalence rate p is small. In this paper, we developed an Empirical Bayes (EB) ...
Models with Transaction Cost for Pricing European Options and Hedging

Oyediran, Oyelami Benjamin (2016)

In this paper models with transaction costs for pricing of European options using mixed fractional Brownian motion (fbm) and Partial differential equation (PDE) model are considered. Investigation on price sensitivity to ...
On the Moment Estimation of Parameters of Triangular Credibility Distribution

Sampath, S.; Renitta, L. Pephine (2016)

In this paper, the problem of estimating underlying parameters of a membership function namely, triangular membership function is considered. Estimation of parameters has been carried out by using two different approaches ...
K-th Upper Record Values from Modified Weibull Distribution and Characterization

Khan, M.A.; Khan, R.U. (2016)

In this paper k  th upper record values from modified Weibull distribution has been studied and some new recurrence relations satisfied by single and product moments are derived. The results obtained are the generalization ...
Inference on the Skew Normal Distribution Using Ranked Set Sampling

Al-Saleh, Mohammad Fraiwan; Aldarabseh, Mahmood Zuhier (2017-05)

The estimation of the skewness parameter of the skew Normal Distribution (SND) using the information in a Ranked Set Sample (RSS) is considered. The estimators obtained are compared with respect to their counterparts using ...
An Almost Sure Central Limit Theorem for Autoregressive Processes

Oprisan, Adina (2017-05)

We consider additive functionals for a class of autoregressive processes and prove that their empirical measures with logarithmic averaging converge almost surely via a martingale decomposition. A method developed in our ...
On Concomitant of Order Statistics from Bivariate Log-Exponentiated Kumarswamy Distribution

Khan, M. J. S.; Kumar, S. (2017-05)

In this article, the distribution of concomitant of order statistics has been obtained from Bivariate log-exponentiated Kumarswamy distribution. The distribution of the th r order statistics and it's concomitant arising ...
Characterization of Burr-Type X Distribution Based on Conditional Expectations of Dual Generalized Order Statistics

Khan, M. I.; Khan, M. A. R. (2017-05)

In this paper, the characterization of Burr -Type X distribution by conditional expectation of function of dual generalized order statistics based on non-adjacent dual generalized order statistics are obtained. Further, ...
Comparative Analysis of Some Volatility Estimators: An Application to Historical Data from the Nigerian Stock Exchange Market

Oyelami, Benjamin Oyediran; Sambo, Eric Erenam (2017-05)

Several models exist for estimating volatility of stocks. In this paper, comparisons are made for the performance characteristics of seven volatility estimators using the data for eleven Banks from the Nigerian Stock ...
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 ...
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 ...
Comparative Study on Estimation of Poisson Parameter in Decision Theoretic Approach

Devi, R. Renuka; Subbiah, M.; Srinivasan, M.R. (2017-11)

It has become imperative in statistical inference to seek beyond the widely practiced squared loss function to accommodate the asymmetric conditions. An attempt in this direction is generally model-specific and the present ...
Comparative Study of District Level Rice Production under Artificial Neural Network and Multiple Linear Regression Model

Tiwari, Neeraj; Agarwal, Ankuri (2017-11)

Using Artificial Neural Network (ANN) methodology a district level prediction of rice production in Uttarakhand state of India has been proposed. The proposed model has been empirically compared with the existing Multiple ...
Additive Randomized Response Model with Known Sensitivity Level

Tiwari, Neeraj; Mehta, Prachi (2017-11)

Randomized Response Technique (RRT) is an indirect survey method to collect sensitive information from the respondent without unveiling his/her true status. RRT has been first developed by Warner [12]. Tiwari & Mehta [11] ...
A Note on the Convexity of a Generalized Pearson Distribution

De la Cruz, J.A.; Singh, J. N.; Shakil, M. (2017-11)

In this paper, we investigate the convexity of a generalized Pearson distribution introduced by Shakil et al. [16], known as Shakil-Kibria-Singh (SKS) distribution, in literature. Several related properties are also discussed.
