accuracy_index: Accuracy Index

In dnzmarcio/ewoc: Escalation with Overdose Control

Description

Calculate the Accuracy Index.

Usage

accuracy_index(
  mtd_estimate,
  dose_set,
  true_prob,
  theta,
  loss = c("squared", "absolute", "classification", "overdose"),
  alpha = NULL
)

Arguments

mtd_estimate	a numerical vector of the MTD estimates.
dose_set	a numerical vector of allowable doses in the trial.
true_prob	a numerical vector of the true probabilities associated with 'dose_set'.
theta	a numerical value defining the proportion of expected patients to experience a medically unacceptable, dose-limiting toxicity (DLT) if administered the MTD.
loss	a loss function between the true probabilities of toxicity 'true_prob' and the target DLT rate 'theta'.
alpha	a numerical value indicating the weight of overdose for the overdose loss function.

Value

Accuracy Index for given loss function of the MTD estimates.
