Parametric Bootstrap Mantel‐Haenszel Statistic for Aggregated Testlet Effects

Journal of Educational Measurement, Volume 62, Issue 4, Page 503-530, Winter 2025.
Abstract While testlets have proven useful for assessing complex skills, the stem shared by multiple items often induces correlations between responses, leading to violations of local independence (LI), which can result in biased parameter and ability estimates.

A Complete Characterization of the Linear, Log-Linear, and Semi-Log Incomplete Demand System Models

Journal of Agricultural and Resource Economics, 2002
This study extends LaFrance's (1985, 1986, 1990) previous research by deriving the necessary parameter restrictions for two additional classes of incomplete demand system models to be integrable.

Bending performance changes during prolonged canine eruption in saber‐toothed carnivores: A case study of Smilodon fatalis

The Anatomical Record, Volume 308, Issue 11, Page 2994-3006, November 2025.
Abstract The canine of saber‐toothed predators represents one of the most specialized dental structures known. Hypotheses about the function of hypertrophied canines range from display and conspecific interaction, soft food processing, to active prey acquisition.

Understanding the war in Ukraine: Comparing knowledge and bias in Russia and the U.S.

Political Psychology, Volume 46, Issue 5, Page 1168-1185, October 2025.
Abstract What mass publics know about foreign affairs is of great importance in international politics. Knowledge and ignorance probabilistically delimit the range of opinions likely to form on foreign affairs issues. Military strategists understand the importance of “information warfare,” since publics apply foreign affairs knowledge to form opinions ...

On the Loglinear Poisson and Gamma Model [PDF]

ASTIN Bulletin, 1980
Maximum likelihood estimation in case of a Poisson or Gamma distribution with loglinear parametrization for the mean is quite akin. The asymptotic variance-covariance matrix for the maximum likelihood estimator is derived as well as a linear estimator, which can serve as a starting value for the nonlinear search procedure.

Loglinear Modelling with Latent Variables: the Case of Mobility Tables [PDF]

, 1988
In this chapter mobility tables of Denmark and Britain will be reanalysed. Following Clogg’s earlier work (Clogg, 1981a, 1981b), a loglinear analysis with latent variables will be presented. The methodology is embedded in the latent structure analysis, developed by Paul F.
