Overview

About

Maintained by Keefe MurphyCRAN page ↗GitHub ↗Issues ↗

Provides flexible Bayesian estimation of Infinite Mixtures of Infinite Factor Analysers and related models, for nonparametrically clustering high-dimensional data, introduced by Murphy et al. (2020) doi:10.1214/19-BA1179. The IMIFA model conducts Bayesian nonparametric model-based clustering with factor analytic covariance structures without recourse to model selection criteria to choose the number of clusters or cluster-specific latent factors, mostly via efficient Gibbs updates. Model-specific diagnostic tools are also provided, as well as many options for plotting results, conducting posterior inference on parameters of interest, posterior predictive checking, and quantifying uncertainty.

Changes in 2.2.0

New Features

get_IMIFA_results gains the arg. adapt, allowing automatic, post-hoc truncation of

redundant factors in cases where mcmc_IMIFA was called with adapt=FALSE only

(provided relevant parameters were stored) for the "IFA", "MIFA", "OMIFA", & "IMIFA" methods.

mgpControl gains the active.crit arg. to allow the criterion for determining the number of

active factors of Schiavon & Canale (2020) to be used (for "IFA" models only); this is available

for both mcmc_IMIFA with adapt=TRUE directly and the aforementioned post-hoc adaptation using

get_IMIFA_results, though the old criterion of Bhattacharya & Dunson (2011), active.crit="BD",

remains the default for all infinite factor models in each case. See documentation for details.

Improvements, Bug Fixes, & Miscellaneous Edits

Models with range.Q=0 now work again for the "FA", "MFA", "OMFA", & "IMFA" methods.

_(with thanks to @abcoxyzide for flagging the issue)_

Show all changes in 2.2.0Hide the rest of the changes in 2.2.0

The mgpControl arg. delta0g now also governs beta.d1, beta.d2, & sigma.hyper, in addition to alpha.d1 & alpha.d2.
Improved documentation & checks related to the Ledermann bound + added various references to, & warnings for, the stricter Q <= floor((P - 1)/2) restriction throughout the package.
Minor fixes for "MFA"/"MIFA" models when mu0g, psi0g, &/or delta0g is TRUE, particularly when length(range.G) > 1.
Minor speed-up to G_priorDensity when discount is non-zero.
Extensive edits to avoid overheads introduced in matrixStats (>= 1.0.0) + related minor speed-ups.
Now using newer CITATION commands & updated License: GPL (>= 3).

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("IMIFA", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("Keefe-Murphy/IMIFA")

Development version from Keefe-Murphy/IMIFA. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-imifa

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-IMIFA

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-IMIFA

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
