default_doc_internal: Unexported documentation helper function.

In shapr: Prediction Explanation with Dependence-Aware Shapley Values

Unexported documentation helper function.

Description

Unexported documentation helper function.

Usage

default_doc_internal(
  internal,
  model,
  predict_model,
  x_explain,
  x_train,
  n_features,
  W_kernel,
  S,
  dt_vS,
  output_size,
  ...
)

Arguments

internal	List. Holds all parameters, data, functions and computed objects used within explain() The list contains one or more of the elements parameters, data, objects, iter_list, timing_list, main_timing_list, output, and iter_timing_list.
model	Objects. The model object that ought to be explained. See the documentation of explain() for details.
predict_model	Function. The prediction function used when model is not natively supported. See the documentation of explain() for details.
x_explain	Data.table with the features of the observation whose predictions ought to be explained (test data).
x_train	Data.table with training data.
n_features	Positive integer. The number of features.
W_kernel	Numeric matrix. Contains all nonscaled weights between training and test observations for all coalitions. The dimension equals ⁠n_train x m⁠.
S	Integer matrix of dimension ⁠n_coalitions x m⁠, where n_coalitions and m equals the total number of sampled/non-sampled coalitions and the total number of unique features, respectively. Note that m = ncol(x_train).
dt_vS	Data.table of dimension n_coalitions times n_explain + 1 containing the contribution function estimates. The first column is assumed to be named id_coalition and containing the ids of the coalitions. The last row is assumed to be the full coalition, i.e., it contains the predicted responses for the observations which are to be explained.
output_size	Scalar integer. Specifies the dimension of the output from the prediction model for every observation.
...	Further arguments passed to approach-specific functions.

Value

The internal list. It holds all parameters, data, and computed objects used within explain().
