MachineShop (version 3.8.0)

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"),
  distr = character(),
  method = character(),
  stats = MachineShop::settings("stats.PartialDependence"),
  na.rm = TRUE
)

Value

PartialDependence class object that inherits from data.frame.

Arguments

object

model fit result.

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").

distr, method

arguments passed to predict.

stats

function, function name, or vector of these with which to compute response variable summary statistics over non-selected predictor variables.

na.rm

logical indicating whether to exclude missing predicted response values from the calculation of summary statistics.
