Description

AutoScore STEP(iii): Generate the initial score with the final list of variables (Re-run AutoScore Modules 2+3)

Usage

AutoScore_weighting(
  train_set,
  validation_set,
  final_variables,
  max_score = 100,
  categorize = "quantile",
  max_cluster = 5,
  quantiles = c(0, 0.05, 0.2, 0.8, 0.95, 1),
  metrics_ci = FALSE
)

Arguments

train_set

A processed data.frame that contains data to be analyzed, for training.

validation_set

A processed data.frame that contains data for validation purpose.

final_variables

A vector containing the list of selected variables, selected from Step(ii)AutoScore_parsimony. Run vignette("Guide_book", package = "AutoScore") to see the guidebook or vignette.

max_score

Maximum total score (Default: 100).

categorize

Methods for categorize continuous variables. Options include "quantile" or "kmeans" (Default: "quantile").

max_cluster

The max number of cluster (Default: 5). Available if categorize = "kmeans".

quantiles

Predefined quantiles to convert continuous variables to categorical ones. (Default: c(0, 0.05, 0.2, 0.8, 0.95, 1)) Available if categorize = "quantile".

metrics_ci

whether to calculate confidence interval for the metrics of sensitivity, specificity, etc.

Value

Generated cut_vec for downstream fine-tuning process STEP(iv) AutoScore_fine_tuning.
