plot_univariate: Scatter plot of density ratios and individual variables

In densityratio: Distribution Comparison Through Density Ratio Estimation

Scatter plot of density ratios and individual variables

Description

A scatter plot showing the relationship between estimated density ratios and individual variables.

Usage

plot_univariate(
  x,
  vars = NULL,
  samples = "both",
  logscale = TRUE,
  grid = FALSE,
  sample.facet = FALSE,
  nrow.panel = NULL,
  tol = 0.01,
  ...
)

Arguments

x	Density ratio object created with e.g., kliep(), ulsif(), or naive()
vars	Character vector of variable names to be plotted.
samples	Character string indicating whether to plot the 'numerator', 'denominator', or 'both' samples. Default is 'both'.
logscale	Logical indicating whether to plot the density ratio estimates on a log scale. Default is TRUE.
grid	Logical indicating whether output should be a list of individual plots ("individual"), or one facetted plot with all variables ("assembled"). Defaults to "individual".
sample.facet	Logical indicating whether to facet the plot by sample, i.e, showing plots separate for each sample, and side to side. Defaults to FALSE.
nrow.panel	Integer indicating the number of rows in the assembled plot. If NULL, the number of rows is automatically calculated.
tol	Numeric indicating the tolerance: values below this value will be set to the tolerance value, for legibility of the plots
...	Additional arguments passed to the predict() function.

Value

Scatter plot of density ratios and individual variables.

Examples

set.seed(123)
# Fit model
dr <- ulsif(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
ulsif(numerator_small, denominator_small, sigma = 2, lambda = 2)
