predict.bassetfit {fido}

Predict using basset

Description

Predict using basset

Usage

## S3 method for class 'bassetfit'
predict(
  object,
  newdata = NULL,
  response = "Lambda",
  size = NULL,
  use_names = TRUE,
  summary = FALSE,
  iter = NULL,
  from_scratch = FALSE,
  ...
)

Arguments

object

An object of class pibblefit

newdata

An optional matrix for which to evaluate prediction.

response

Options = "Lambda":Mean of regression, "Eta", "Y": counts

size

the number of counts per sample if response="Y" (as vector or matrix), default if newdata=NULL and response="Y" is to use colsums of m$Y. Otherwise uses median colsums of object$Y as default. If passed as a matrix should have dimensions ncol(newdata) x iter.

use_names

if TRUE apply names to output

summary

if TRUE, posterior summary of predictions are returned rather than samples

iter

number of iterations to return if NULL uses object$iter

from_scratch

should predictions of Y come from fitted Eta or from predictions of Eta from posterior of Lambda? (default: false)

...

other arguments passed to summarise_posterior

Details

currently only implemented for pibblefit objects in coord_system "default" "alr", or "ilr".

Value

(if summary==FALSE) array D x N x iter; (if summary==TRUE) tibble with calculated posterior summaries
