Inference in simple regression for the intercept utilizing prior information on the slope
( Wayne State University , 2011 , Article)Shrinkage type estimators are developed for the intercept parameter of a simple linear regression model and the case when it is suspected a priori that the slope parameter is equal to some specific value is considered. ... -
Empirical likelihood inference for population quantiles with unbalanced ranked set samples
( Taylor & Francis Group , 2011 , Article)We consider nonparametric interval estimation for the population quantiles based on unbalanced ranked set samples. We derived the large sample distribution of the empirical log likelihood ratio statistic for the quantiles. ... -
Confidence intervals for quantiles using record values from the generalized exponential distribution
( Nova Science Publishers, Inc. , 2012 , Book chapter)Likelihood-based and bootstrap confidence intervals for the quantiles of the generalized exponential distribution based on record values are developed. Intervals for the difference of quantiles based on two independent ... -
Interval estimation of the stress-strength reliability in the two-parameter exponential distribution based on records
( Taylor and Francis Ltd. , 2014 , Article)We consider interval estimation of the stress-strength reliability in the two-parameter exponential distribution based on records. We constructed Bayesian intervals, Bootstrap intervals and intervals using the generalized ... -
Confidence intervals for the two-parameter exponential reliability with type II censored data
( Taylor and Francis Ltd. , 2016 , Article)We consider interval estimation of the reliability of the two-parameter exponential distribution.We consider asymptotic intervals, Bayesian, as well as intervals based on the generalized pivot variable. Transformations to ... -
Interval Estimation in Lifetime Distributions Using Progressively Type II Censored Data
( World Scientific , 2022 , Article)In this paper, we developed a method for constructing confidence intervals for the parameters of lifetime distributions based on progressively type II censored data. The method produces closed form expressions for the ... -
Improved Likelihood Inference Procedures for the Logistic Distribution
( MDPI , 2022 , Article)We consider third-order likelihood inferences for the parameters, quantiles and reliability function of the logistic distribution. This theory involves the conditioning and marginalization of the likelihood function. The ... -
Refined Inference on the Scale Parameter of the Generalized Logistic Distribution Based on Adjusted Profile Likelihood Functions
( MDPI , 2022 , Article)We consider inference based on the profile likelihood function for the scale parameter of the generalized logistic distribution. This distribution is a generalization of the logistic distribution, a symmetric distribution ... -
Maximum Likelihood Estimation in the Inverse Weibull Distribution with Type II Censored Data
( Horizon Research Publishing , 2022 , Article)We consider maximum likelihood estimation for the parameters and certain functions of the parameters in the Inverse Weibull (IW) distribution based on type II censored data. The functions under consideration are the Mean ... -
An attribute control chart for the inverse Weibull distribution under truncated life tests
( Elsevier Ltd , 2022 , Article)Statistical Process Control (SPC) is applied to monitor production processes in order to discover any problems or issues that may arise during the production process and to help in finding solutions for these issues. In ... -
Coins from Al-Zubarah, Qatar: A historical-scientific study
( Magnus Group LLC , 2021 , Conference Paper)A surface archaeological coins “Zu/111 found at the old town of Al-Zubarah, Qatar” has been analysed complementarily using historic and scientific characterization techniques. For example, a scanning electron microscope ... -
ESTIMATION OF THE LOCATION-SCALE PARAMETERS BASED ON RANKED SET SAMPLING COMBINED WITH ADDITIONAL BINOMIAL INFORMATION
( ISOSS PUBLICATIONS , 2023 , Article)In this paper, we propose a modified version of ranked set sample which allows for the incorporation of more information in the inference procedure at almost no cost. This procedure is studied for the location-scale family ... -
Inference Based on New Pareto-Type Records With Applications to Precipitation and Covid-19 Data
( International Academic Press , 2023 , Article)We consider estimation and prediction of future records based on observed records from the new Pareto type distribution proposed recently by Bourguignon et al. (2016), ¡°M. Bourguignon, H. Saulo, R. N. Fernandez, A new ... -
Turning point in COVID-19 severity and fatality during the pandemic: a national cohort study in Qatar
( BMJ Publishing Group , 2023 , Article)Objective To assess the evolution of COVID-19 severity and fatality in a unique setting that consistently applied, throughout the pandemic, rigorous and standardised criteria for defining severe COVID-19 outcomes. Methods ... -
History of primary-series and booster vaccination and protection against Omicron reinfection
( American Association for the Advancement of Science , 2023 , Article)Laboratory evidence suggests a possibility of immune imprinting for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We investigated the differences in the incidence of SARS-CoV-2 reinfection in a ... -
Student perspectives on the integration of artificial intelligence into healthcare services
( SAGE Publications Inc. , 2023 , Article)Background: Healthcare workers are often overworked, underfunded, and face many challenges. Integration of artificial intelligence into healthcare service provision can tackle these challenges by relieving burdens on ... -
Organoboronic acids/esters as effective drug and prodrug candidates in cancer treatments: challenge and hope
( Taylor and Francis Ltd. , 2023 , Article Review)Boronic acids/esters have recently emerged in the field of medicinal and pharmaceutical research due to their exceptional oxophilicity, low toxicity, and unique structure. They are known as potent enzyme inhibitors, cancer ... -
Metal Organic Frameworks, Their Properties and Future Promises in the Medical Field
( Nova Science Publishers, Inc. , 2021 , Book chapter)Nanotechnology is defined as the manipulation of matter at the atomic and molecular level, with nanomedicine being a subdivision of nanotechnology, where nanoparticles are used in medicine often as a drug delivery vehicle ... -
Studies on metal–organic framework (MOF) nanomedicine preparations of sildenafil for the future treatment of pulmonary arterial hypertension
( nature , 2021 , Article)Pulmonary arterial hypertension (PAH) is an incurable disease, although symptoms are treated with a range of dilator drugs. Despite their clinical benefits, these drugs are limited by systemic side-effects. It is, therefore, ... -
