Drought analysis and short-term forecast in the Aison River Basin (Greece) [PDF]
Natural Hazards and Earth System Sciences, 2012 A combined regional drought analysis and forecast is elaborated and applied to the Aison River Basin (Greece). The historical frequency, duration and severity were estimated using the standardized precipitation index (SPI) computed on variable time ...

Bayes factors and the geometry of discrete hierarchical loglinear models
, 2011 A standard tool for model selection in a Bayesian framework is the Bayes factor which compares the marginal likelihood of the data under two given different models.

Minimum phi-divergence estimator and hierarchical testing in loglinear models [PDF]
, 2000 In this paper we consider inference based on very general divergence measures, under assumptions of multinomial sampling and loglinear models. We define the minimum phi-divergence estimator, which is seen to be a generalization of the maximum likelihood ...

Antenatal dexamethasone for late preterm delivery: Rate of complete course and neonatal outcomes
International Journal of Gynecology &Obstetrics, Volume 171, Issue 3, Page 1180-1188, December 2025.Abstract Objective This retrospective cohort study aimed to assess the rate of complete dexamethasone administration among late preterm deliveries and its impact on neonatal outcomes. Methods We reviewed medical records of 1500 late preterm deliveries (gestational age 34–36 + 6 weeks) between January 2018 and December 2020, analyzing baseline ...

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.

prefmod: An R Package for Modeling Preferences Based on Paired Comparisons, Rankings, or Ratings
Journal of Statistical Software, 2012 The first part of this paper describes a series of loglinear preference models based on paired comparisons, a method of measurement whose aim is to order a set of objects according to an attribute of interest by asking subjects to compare pairs of ...

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.
