Obtain predicted density ratio values from a naivedensityratio object

Description

Obtain predicted density ratio values from a naivedensityratio object

Usage

## S3 method for class 'naivedensityratio'
predict(object, newdata = NULL, log = FALSE, tol = 1e-06, ...)

Arguments

object	A naive object
newdata	Optional matrix new data set to compute the density
log	A logical indicating whether to return the log of the density ratio
tol	Minimal density value to avoid numerical issues
...	Additional arguments to be passed to the function

Value

An array with predicted density ratio values from possibly new data, but otherwise the numerator samples.

Examples

set.seed(123)
# Fit model
dr <- naive(numerator_small, denominator_small)
# Inspect model object
dr
# Obtain summary of model object
summary(dr)
# Plot model object
plot(dr)
# Plot density ratio for each variable individually
plot_univariate(dr)
# Plot density ratio for each pair of variables
plot_bivariate(dr)
# Predict density ratio and inspect first 6 predictions
head(predict(dr))
# Fit model with custom parameters
naive(numerator_small, denominator_small, m=2, kernel="epanechnikov")
