surv_ceteris_paribus: Helper functions for predict_profile.R

Description

Helper functions for predict_profile.R

Helper functions for predict_profile.R

Usage

surv_ceteris_paribus(x, ...)

# S3 method for surv_explainer surv_ceteris_paribus( x, new_observation, variables = NULL, categorical_variables = NULL, variable_splits = NULL, grid_points = 101, variable_splits_type = "uniform", center = FALSE, output_type = "survival", ... )

Value

A data.frame containing the result of the calculation.

Arguments

x

an explainer object - model preprocessed by the explain() function

...

other parameters, currently ignored

new_observation

a new observation for which predictions need to be explained

variables

character, names of the variables to be included in the calculations

categorical_variables

character vector, names of variables that should be treated as categories (factors are included by default)

variable_splits

named list of splits for variables, in most cases created with internal functions. If NULL then it will be calculated based on validation data available in the explainer

grid_points

maximum number of points for profile calculations. Note that the final number of points may be lower than grid_points. Will be passed to internal function. By default 101.

variable_splits_type

character, decides how variable grids should be calculated. Use "quantiles" for percentiles or "uniform" (default) to get uniform grid of points.
