The ordinalbayes R package was developed for fitting
ordinal Bayesian models when there is a high-dimensional covariate
space, such as when high-throughput genomic data are used in modeling
the ordinal outcome. This package depends on the runjags R
package and JAGS (version >=4.x.x) must be installed as well. See the
JAGS and
[runjags] (https://CRAN.R-project.org/package=runjags) for
installation instructions. The package includes the function
ordinalbayes which can be used to fit LASSO
(model = "lasso"), normal spike-and-slab
(model = "normalss"), double exponential spike-and-slab
(model = "dess"), and regression-based variable inclusion
indicator Bayesian models (model = "regressvi"). Variable
selection can be performed using Bayes factor or using the posterior
distributions of the variable inclusion indicators directly. This
vignette describes the syntax required for each of our Bayesian
models.

#> TCGA-EA-A97N-01A-11R-A38B-07 1.259106 4.805752The primary function for model fitting in the
ordinalbayes package is ordinalbayes. The
function arguments are
args(ordinalbayes)
#> function (formula, data, x = NULL, subset, center = TRUE, scale = TRUE,
#> a = 0.1, b = 0.1, model = "regressvi", gamma.ind = "fixed",
#> pi.fixed = 0.05, c.gamma = NULL, d.gamma = NULL, alpha.var = 10,
#> sigma2.0 = NULL, sigma2.1 = NULL, coerce.var = 10, lambda0 = NULL,
#> nChains = 3, adaptSteps = 5000, burnInSteps = 5000, numSavedSteps = 9999,
#> thinSteps = 3, parallel = TRUE, seed = NULL, quiet = FALSE)
#> NULLThe ordinalbayes function accepts a model
formula that specifies the ordinal outcome on the left-hand
side of the equation and any unpenalized predictor variable(s) from the
phenotypic dataset on the right-hand side of the ∼ equation; if no unpenalized predictor
variables are included, the model formula includes 1 (the intercept) on
the right-hand side of the equation. Unpenalized predictors are those
that we want to coerce into the model (e.g., age) so that no penalty is
applied. When unpenalized predictors are included (or coerced) into the
model, the user can specify the variance associated with those model
parameters (default coerce.var=10).
For example, this call fits a regression-based variable inclusion
indicator Bayesian model to predict the ordinal outcome
Stage where cigarettes_per_day+age_at_index
and age_at_index are included as unpenalized predictors
(coerced into the model) and the expression of 41 genes are included as
penalized predictors. The user should pass to x the genomic
feature data (e.g., expression of genes from high-throughput assays) to
be penalized in the fitted model, which are in columns 5-45 of the
cesc data.frame. Here a fixed constant prior for πj is set to
0.05. To shorten run time for demonstration purposes, we reduced the
number of iterations for adaptation (adaptSteps), the
number of iterations of the Markov chain to run
(burnInSteps), and the number of saved steps per chain
(numSavedSteps) for all examples.

subset=(race=="white").
The LASSO Bayesian ordinal model can be fit by specifying
model="lasso" which assumes the penalized coefficients
βj for
j = 1, …, P are from
independent Laplace (or double exponential) distributions with parameter
λ which is from a Gamma
distribution with parameters a and b. The
default parameters are a=0.01 and b=0.01.
Like the LASSO model, the regression-based variable inclusion
indicator model assumes the penalized coefficients βj for j = 1, …, P are from
independent Laplace (or double exponential) distributions with parameter
λ which is from a Gamma
distribution with parameters a and b.
Additionally, a variable inclusion indicator γj is assumed to
follow a Bernoulli distribution with parameter πj. The user can
use either a fixed (gamma.ind="fixed") or random
(gamma.ind="random") prior for πj. When
gamma.ind="fixed", the user can specify
pi.fixed as the constant prior to be some value the (0, 1)
interval (default is 0.05). Here there are no unpenalized covariates
included in the model so the right-hand side of the model formula is
1.
fit.regressvi.fixed<-ordinalbayes(Stage~1, data=cesc,x=cesc[, 5:45], model="regressvi", gamma.ind="fixed", pi.fixed=0.05, adaptSteps=500, burnInSteps=500, numSavedSteps=999)When gamma.ind="random", the user must specify parameter
values for the Beta distribution c.gamma (e.g., 0.01) and
d.gamma (e.g. 0.19).
The normal spike-and-slab Bayesian ordinal model can be fit by
specifying model="normalss". When fitting this model the
user is required to specify the variance for the spike by setting
sigma2.0 to a small positive value (e.g., 0.01) and
variance for the slab by setting sigma2.1 to a large
positive value (e.g., 10). Additionally, a variable inclusion indicator
γj is
assumed to follow a Bernoulli distribution with parameter πj. The user can
use either a fixed (gamma.ind="fixed") or random
(gamma.ind="random") prior for πj. When
gamma.ind="fixed", the user can specify
pi.fixed as the constant prior to be some value the (0, 1)
interval (default is 0.05). Here there are no unpenalized covariates
included in the model so the right-hand side of the model formula is
1.
fit.normalss.fixed<-ordinalbayes(Stage~1, data=cesc,x=cesc[, 5:45], model="normalss", gamma.ind="fixed", pi.fixed = 0.05, sigma2.0=0.01, sigma2.1=10, adaptSteps=500, burnInSteps=500, numSavedSteps=999)When gamma.ind="random", the user must specify parameter
values for the Beta distribution c.gamma (e.g., 0.01) and
d.gamma (e.g. 0.19).
The double exponential spike-and-slab ordinal model can be fit by
specifying model="dess". Like LASSO and , the slab is taken
to be a double exponential distribution with parameter λ which follows a Gamma distribution
with parameters a and b. When fitting this
model the user is required to specify the parameter for the spike (λ0) using
lambda0 (e.g., 20). Additionally, a variable inclusion
indicator γj is assumed to
follow a Bernoulli distribution with parameter πj. The user can
use either a fixed (gamma.ind="fixed") or random
(gamma.ind="random") prior for πj. When
gamma.ind="fixed", the user can specify
pi.fixed as the constant prior to be some value the (0, 1)
interval (default is 0.05). Here there are no unpenalized covariates
included in the model so the right-hand side of the model formula is
1.
fit.dess.fixed<-ordinalbayes(Stage~1, data=cesc,x=cesc[, 5:45], model="dess", gamma.ind="fixed", pi.fixed = 0.05, lambda0=20, adaptSteps=500, burnInSteps=500, numSavedSteps=999)When gamma.ind="random", the user must specify parameter
values for the Beta distribution c.gamma (e.g., 0.01) and
d.gamma (e.g. 0.19).
Generic functions for the resulting ordinalbayes object
are available for extracting meaningful results from the resulting MCMC
chain. The print function returns several summaries from
the MCMC output for each parameter monitored including: the 95th lower
confidence limit for the highest posterior density (HPD) credible
interval (Lower95), the median value (Median), the 95th upper confidence
limit for the HPD credible interval (Upper95), the mean value (Mean),
the sample standard deviation (SD), the mode of the variable (Mode), the
Monte Carlo standard error (MCerr,) percent of SD due to MCMC (MC%ofSD),
effective sample size (SSeff), autocorrelation at a lag of 30 (AC.30),
and the potential scale reduction factor (psrf).
