Log-Normal or Over-Dispersed Poisson?
Risks, 2018 Although both over-dispersed Poisson and log-normal chain-ladder models are popular in claim reserving, it is not obvious when to choose which model. Yet, the two models are obviously different. While the over-dispersed Poisson model imposes the variance

A hierarchical poisson log-normal model for network inference from RNA sequencing data. [PDF]
PLoS ONE, 2013 Gene network inference from transcriptomic data is an important methodological challenge and a key aspect of systems biology. Although several methods have been proposed to infer networks from microarray data, there is a need for inference methods able ...

Misspecification Tests for Log-Normal and Over-Dispersed Poisson Chain-Ladder Models
Risks, 2018 Despite the widespread use of chain-ladder models, so far no theory was available to test for model specification. The popular over-dispersed Poisson model assumes that the over-dispersion is common across the data.

Zero-inflation in the Multivariate Poisson Lognormal Family
Statistics and ComputingAbstract Analyzing high-dimensional count data is a challenge and statistical model-based approaches provide an adequate and efficient framework thatpreserves explainability. The (multivariate) Poisson-Log-Normal (PLN) modelis one such model: it assumes count data are driven by an underlying structuredlatent Gaussian variable, so that the ...
