Summary Method for ocf.marginal Objects

Summarizes an ocf.marginal object.

# S3 method for class 'ocf.marginal'
summary(object, latex = FALSE, ...)

Arguments

object

An ocf.marginal object.

latex

If TRUE, prints LATEX code.

...

Further arguments passed to or from other methods.

Value

Summarizes an ocf.marginal object.

Details

Compilation of the LATEX code requires the following packages: booktabs, float, adjustbox. If standard errors have been estimated, they are printed in parenthesis below each point estimate.

Examples

## Generate synthetic data.
set.seed(1986)

data <- generate_ordered_data(100)
sample <- data$sample
Y <- sample$Y
X <- sample[, -1]

## Fit ocf.
forests <- ocf(Y, X)

## Marginal effects at the mean.
me <- marginal_effects(forests, eval = "atmean")
