Description Usage Arguments Value Author(s) See Also Examples

View source: R/marginal.R

marginal function for the clogitboost objects, which produces the marginal utility values of a covariate.

1	marginal(x, grid, d)

`x`	output object from the `clogitboost` function.
`d`	integer indicating which covariate is used.
`grid`	grid of values for predicting the marginal utilities.

The method marginal returns a vector of predicted marginal utilities based on the grid input.
