Analyzing Non‐Random Selectivity in Online Job Advertisements Using Eurostat Benchmark Data and Generalized Sample Selection Models: An Application to EU Regional Labor Markets

LABOUR, Volume 40, Issue 2, Page 131-161, June 2026.
ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...

Bayesian analysis of Poisson regression with lognormal unobserved heterogeneity : with an application to the patent-R&D relationship

, 2010
This article considers explicit and detailed theoretical and empirical Bayesian analysis of the well-known Poisson regression model for count data with unobserved individual effects based on the lognormal, rather than the popular negative binomial ...

PLNseq: a multivariate Poisson lognormal distribution for high‐throughput matched RNA‐sequencing read count data

, 2015
High‐throughput RNA‐sequencing (RNA‐seq) technology provides an attractive platform for gene expression analysis. In many experimental settings, RNA‐seq read counts are measured from matched samples or taken from the same subject under multiple treatment

Sensing Coverage Prediction for Wireless Sensor Networks in Shadowed and Multipath Environment

The Scientific World Journal, 2013
Sensing coverage problem in wireless sensor networks is a measure of quality of service (QoS). Coverage refers to how well a sensing field is monitored or tracked by the sensors.

Word Length in Political Public Speaking: Distribution and Time Evolution

Entropy
In this paper, word length in the texts of public speeches by USA and UK politicians is analyzed. More than 300 speeches delivered over the past two hundred years were studied. It is found that the lognormal distribution better describes the distribution

Biases in the Maximum Simulated Likelihood Estimation of the Mixed Logit Model

Econometrics
In a recent study, it was demonstrated that the maximum simulated likelihood (MSL) estimator produces significant biases when applied to the bivariate normal and bivariate Poisson-lognormal models.

Evaluating Parameter Uncertainty in the Poisson Lognormal Model with Corrected Variational Estimators

Count data analysis is essential across diverse fields, from ecology and accident analysis to single-cell RNA sequencing (scRNA-seq) and metagenomics. While log transformations are computationally efficient, model-based approaches such as the Poisson-Log-Normal (PLN) model provide robust statistical foundations and are more amenable to extensions.

An ergodicity result for adaptive Langevin algorithms [PDF]

, 2009
We consider a class of adaptive MCMC algorithms using a Langevin-type proposal density. We prove that these are algorithms are ergodic when the target density has exponential tail behaviour.

Host genotype shapes the foliar fungal microbiome of balsam poplar (Populus balsamifera)

, 2013
Foliar fungal communities of plants are diverse and ubiquitous. In grasses endophytes may increase host fitness; in trees, their ecological roles are poorly understood.
