check_fitted_values {vimp}

Check pre-computed fitted values for call to vim, cv_vim, or sp_vim

Description

Check pre-computed fitted values for call to vim, cv_vim, or sp_vim

Usage

check_fitted_values(
  Y = NULL,
  f1 = NULL,
  f2 = NULL,
  cross_fitted_f1 = NULL,
  cross_fitted_f2 = NULL,
  sample_splitting_folds = NULL,
  cross_fitting_folds = NULL,
  cross_fitted_se = TRUE,
  V = NULL,
  ss_V = NULL,
  cv = FALSE
)

Arguments

Y

the outcome

f1

estimator of the population-optimal prediction function using all covariates

f2

estimator of the population-optimal prediction function using the reduced set of covariates

cross_fitted_f1

cross-fitted estimator of the population-optimal prediction function using all covariates

cross_fitted_f2

cross-fitted estimator of the population-optimal prediction function using the reduced set of covariates

sample_splitting_folds

the folds for sample-splitting (used for hypothesis testing)

cross_fitting_folds

the folds for cross-fitting (used for point estimates of variable importance in cv_vim and sp_vim)

cross_fitted_se

logical; should cross-fitting be used to estimate standard errors?

V

the number of cross-fitting folds

ss_V

the number of folds for CV (if sample_splitting is TRUE)

cv

a logical flag indicating whether or not to use cross-fitting

Details

Ensure that inputs to vim, cv_vim, and sp_vim follow the correct formats.

Value

None. Called for the side effect of stopping the algorithm if any inputs are in an unexpected format.
