mongrel-deprecated: mongrel

Description

This function is deprecated, please use pibble instead.

Usage

mongrel(
  Y = NULL,
  X = NULL,
  upsilon = NULL,
  Theta = NULL,
  Gamma = NULL,
  Xi = NULL,
  init = NULL,
  pars = c("Eta", "Lambda", "Sigma"),
  ...
)

Value

An object of class pibblefit

Arguments

Y

D x N matrix of counts (if NULL uses priors only)

X

Q x N matrix of covariates (design matrix) (if NULL uses priors only, must be present to sample Eta)

upsilon

dof for inverse wishart prior (numeric must be > D) (default: D+3)

Theta

(D-1) x Q matrix of prior mean for regression parameters (default: matrix(0, D-1, Q))

Gamma

QxQ prior covariance matrix (default: diag(Q))

Xi

(D-1)x(D-1) prior covariance matrix (default: ALR transform of diag(1)*(upsilon-D)/2 - this is essentially iid on "base scale" using Aitchison terminology)

init

(D-1) x Q initialization for Eta for optimization

pars

character vector of posterior parameters to return
