The Poisson distribution is a special case of the binomial distribution that it models discrete events. It expresses the probability of a number of relatively rare events occurring in a fixed time if ...

The Poisson lognormal model and variants (Chiquet et al. 2021) can be used for a variety of multivariate problems when count data are at play. This package implements efficient variational algorithms ...

Abstract: In this paper a methodology is presented to quantify the year-to-year variability of the lightning outage rate of transmission lines based on the stochastic and climatological variations in ...

Meiotic crossovers (COs) are required for accurate chromosome segregation and mix parental genomes to generate genetically diversified gametes. The distribution of COs among chromosomes is not random.

Advances in single-cell RNA sequencing have allowed for the identification of cellular subtypes on the basis of quantification of the number of transcripts in each cell. However, cells might also ...
