dependence: Partial Dependence

Description

Calculate partial dependence of a response on select predictor variables.

Usage

dependence(object, data = NULL, select = NULL, interaction = FALSE,
  n = 10, intervals = c("uniform", "quantile"), stats = c(Mean =
  base::mean))

Arguments

object

MLModelFit object.

data

data.frame containing all predictor variables. If not specified, the training data will be used by default.

select

expression indicating predictor variables for which to compute partial dependence (see subset for syntax) [default: all].

interaction

logical indicating whether to calculate dependence on the interacted predictors.

n

number of predictor values at which to perform calculations.

intervals

character string specifying whether the n values are spaced uniformly ("uniform") or according to variable quantiles ("quantile").

stats

function, one or more function names, or list of named functions with which to aggregate the response variable over the non-selected predictor variables.

Value

PartialDependence class object that inherits from data.frame.
