Predict either posterior probabilities for each group or latent positions based on new samples
an R6 object with class PLNmixturefit
A data frame in which to look for variables, offsets and counts with which to predict.
The type of prediction required. The default posterior are posterior probabilities for each group ,
response is the group with maximal posterior probability and latent is the averaged latent in the latent space,
with weights equal to the posterior probabilities.
User-specified prior group probabilities in the new data. The default uses a uniform prior.
a list-like structure for controlling the fit. See PLNmixture_param() for details.
additional parameters for S3 compatibility. Not used
A matrix of posterior probabilities for each group (if type = "posterior"), a matrix of (average) position in the latent space (if type = "position") or a vector of predicted groups (if type = "response").
