Fit the multivariate Poisson lognormal model with a variational algorithm. Use the (g)lm syntax for model specification (covariates, offsets, weights).
PLN(formula, data, subset, weights, control = PLN_param())
an object of class "formula": a symbolic description of the model to be fitted.
an optional data frame, list or environment (or object coercible by as.data.frame to a data frame) containing the variables in the model. If not found in data, the variables are taken from environment(formula), typically the environment from which PLN is called.
an optional vector specifying a subset of observations to be used in the fitting process.
an optional vector of observation weights to be used in the fitting process.
a list-like structure for controlling the optimization, with default generated by
PLN_param(). See the associated documentation
an R6 object with class
