Generalized Linear Latent Variable Models (original) (raw)

gllvm is an R package for analysing multivariate ecological data with Generalized Linear Latent Variable Models (GLLVM). Estimation is performed using maximum likelihood estimation, together with either variational approximation (VA) or Laplace approximation (LA) method to approximate the marginal likelihood.

Installation

From CRAN you can install the package using:

install.packages("gllvm")

Or the development version of gllvm from github with the help of devtools package using:

devtools::install_github("JenniNiku/gllvm")
