Exploring Discrete Factor Analysis with the discFA Package in R
Reza Arabi Belaghi, Yasin Asar, Rolf Larsson
Literature suggested that using the traditional factor analysis for the count data may be inappropriate. With that in mind, discrete factor analysis builds on fitting systems of de…

Bartlett correction of an independence test in a multivariate Poisson model
Rolf Larsson
We consider a system of dependent Poisson variables, where each variable is the sum of an independent variate and a common variate. It is the common variate that creates the depend…

Discrete factor analysis
Rolf Larsson
In this paper, we present a method for factor analysis of discrete data. This is accomplished by fitting a dependent Poisson model with a factor structure. To be able to analyze or…
