The department offers programs leading to the award of Bachelor of Science in Statistics (BSc. Statistics), Master Science in Statistics (MSc. Statistics) and Doctor of Philosophy in Statistics (PhD. Statistics). It also offers a special minor in Health Statistics which is designed for students pursuing careers as Statisticians in the Ministry of Health. A general minor in Statistics is also offered to students of other majors at the College of Science.

All these programs were in place prior to the existence of the department, so a bit of history is in order. The bachelor degree in Statistics started 1993, together with degrees in Mathematics and Computer Science, under the then department of Mathematics and Computing (DOMAC). The Department of Computer Science became a separate department in September 1995, and DOMAC became the Department of Mathematics and Statistics (DOMAS). The other statistics programs that started under the DOMAS  are the minor in Health Statistics (1998), Master of Science in Statistics (1999) and PhD in Statistics (2010).

PhD Students' Research

Below are some of the ongoing PhD research studies at the Department of Statistics:

Title:

Skewed Elliptical Distributions and their Applications: [PhD Student: Iman Al Hashmi - 47910]

Summary:

The main objectives of the proposed research are to construct a new ECD and skewed ECD, and investigate their mathematical properties as well as to use the constructed distributions in applied contexts and compare their performances with the existing results.

Title:

On multivariate classification and minimization of misclassification rates: [PhD Student: Mubarak Al Shukeili - 29026]

Summary:

The main objective of the study is to develop statistical model aimed to generate optimal separable hyperplanes that minimizes the MCR. Performance of other classification methods and techniques will be studied theoretically. A method based on the MM Principle will be developed. New classification method based on the support vector machine (SVM) will be proposed and validated theoretically and numerically using simulated and real life data.

Title:

Bias reduction in parameter estimation under missing data conditions: [PhD Student: Muna Al Shaaibi - 46933]

Summary:

The main objective of this study is propose a method of estimating parameters under data missingness condictions. The EM algorithm and MI are popular methods for dealing with missing data which show superiority over the traditional methods. Inspite of these efforts, parameters derived from these methods are still associated with high biases in the estimated parameters. Missing data present various problems. The proposed method will be validated and its performance compared with the current methods using simulation studies as well as real life data.

Title:

Parametric sub-distribution hazard model for clustered competing risks: [PhD Student: Noora Al Shanfari - 11906]

Summary: 

The main objective of this study is to analyse clustered competi g risk data using parametric approach. In the presence of competing, two different models can be used to analyze competing risk data, the cause-specific hazard model and the subdistribution hazard model. The latter model is used to estimate the effect of the covariates on the cumulative incidence function. However, in medical research, there are applications involving competing risks where individuals may be correlated. in this case, two models can be fit, the frailty model and the marginalized model. Marginal models have a population-averaged interpretation. Few attempts have been made for modeling clustered competing risk data using marginalized models. However, until now no attempts have been made using a parametric approach.

Data Science Analytics Lab

Overview

The Data Science Analytics Lab (DSAL) is an initiative whose primary objective is to develop relevant statistical theory for specific data types so as to generate required knowledge to support sustainable development.

Vision

To be a leading Centre of excellence for statistical research, innovations and applications

Objectives

1. To develop statistical theory, algorithms and systems for knowledge extraction and visualization

2. To generate information on patterns, insights and predictions from diverse data for various applications

3. To develop a database of relevant statistical information for timely, evidence-based decision making for sustainable development

4. To develop collaboration across users and producers of statistical information through capacity building.

Activities

1. Collaborative statistical and applications research at national, regional and international levels

2. Capacity building in statistical knowledge and the use of statistical packages, such as R programming language

3. Support industry, policy makers with workable optimal solutions to solve local problems through attachments.
