  Authors:Laixu Shang, Ping-Feng Xu, Na Shan, Man-Lai Tang, and George To-Sum HoFrom:PLoS ONE (Vol. 18, Issue 1) Peer-Reviewed

  Jan. 17, 20238,706 words Report 1600LOne 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...

• GENEROSITY ACROSS THE INCOME AND WEALTH DISTRIBUTIONS.

  Authors:Jonathan Meer and Benjamin A. PridayFrom:National Tax Journal (Vol. 74, Issue 3) Peer-Reviewed

  Sept. 202111,467 words Article 1430LThere 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...

• Likelihood ratios: Clinical application in day-to-day practice

  Authors:Rajul Parikh, Shefali Parikh, Ellen Arun, and Ravi ThomasFrom:Indian Journal of Ophthalmology (Vol. 57, Issue 3) Peer-Reviewed

  May-June 20094,018 words Report Byline: 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...

• Polychotomous logistic model with missing values

  Authors:M. Karimlou, Gh. Jandaghi, K. Azam, Grami, and K. MohammadFrom:Advances in Natural and Applied Sciences (Vol. 3, Issue 3) Peer-Reviewed

  Sept. 20092,578 words Report In 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 data

  Authors:Yafeng Xia and Hu DaFrom:Journal of Probability and StatisticsPeer-Reviewed

  Annual 20143,115 words Report 1380LBlock 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...

• Sensitivity estimates from characteristic functions

  Authors:Paul Glasserman and Zongjian LiuFrom:Operations Research (Vol. 58, Issue 6) Peer-Reviewed

  November-December 20109,760 words Article 1470LThe 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.

  Authors:Ruiwei Jiang, Siqian Shen, and Yiling ZhangFrom:Operations Research (Vol. 65, Issue 6) Peer-Reviewed

  Nov-Dec 201711,977 words Article 1730LWe 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...
