Accelerating L.sub.1-penalized expectation maximization algorithm for latent variable selection in multidimensional two-parameter logistic models.One of the main concerns in multidimensional item response theory (MIRT) is to detect the relationship between observed items and latent traits, which is typically addressed by the exploratory analysis and factor...
From:National Tax Journal (Vol. 74, Issue 3) Peer-ReviewedThere is little systematic evidence on the relationship between income, wealth, and charitable giving, despite its importance for the provision of public goods. We use the Panel Study of Income Dynamics to provide...
From:Indian Journal of Ophthalmology (Vol. 57, Issue 3) Peer-ReviewedByline: Rajul. Parikh, Shefali. Parikh, Ellen. Arun, Ravi. Thomas In this article we provide an introduction to the use of likelihood ratios in clinical ophthalmology. Likelihood ratios permit the best use of...
From:Advances in Natural and Applied Sciences (Vol. 3, Issue 3) Peer-ReviewedIn health studies, we often face some variable missing. This missingness can happen in either response or other covariates. In this paper, the discussion focuses on missing covariates. A method is proposed for analysis...

Block empirical likelihood for semiparametric varying-coefficient partially linear errors-in-variables models with longitudinal dataBlock empirical likelihood inference for semiparametric varying-coefficient partially linear errors-in-variables models with longitudinal data is investigated. We apply the block empirical likelihood procedure to...
From:Operations Research (Vol. 58, Issue 6) Peer-ReviewedThe likelihood ratio method (LRM) is a technique for estimating derivatives of expectations through simulation. LRM estimators are constructed from the derivatives of probability densities of inputs to a simulation. We...

Integer Programming Approaches for Appointment Scheduling with Random No-Shows and Service Durations.We consider a single-server scheduling problem given a fixed sequence of appointment arrivals with random no-shows and service durations. The probability distribution of the uncertain parameters is assumed to be...
