predict.bfa: Posterior predictive and univariate conditional posterior predictive distributions

Description

Posterior predictive and univariate conditional posterior predictive distributions, currently implemented only for Gaussian copula models. If resp.var is not NA, returns an estimate of the conditional cdf at every observed data point for each MCMC iterate. If resp.var is NA, returns draws from the joint posterior predictive.

Usage

"predict"(object, resp.var = NA, cond.vars = NA, numeric.as.factor = TRUE, ...)

Arguments

object

bfa model object

resp.var

Either a character vector (length 1) with name of the response variable for conditional, or NA for draws from the joint posterior predictive.

cond.vars

Conditioning variables; either a list like list(X1=val1, X2=val2) with X1, X2 variables in the original data frame, or a P length vector with either the conditioning value or NA (for marginalized variables). Ignored if resp.var is NA

numeric.as.factor

Treat numeric variables as ordinal when conditioning

...

Ignored

Value

A matrix where each row is either a sample of the conditional posterior predictive cdf at each datapoint, or a single sample from the joint posterior predictive.
