opt.dose {JQL}

Optimal Interval-valued Dose under the Individualized Interval-valued Dose Rule via (Residual) Jump Q-learning.

Description

This function assigns each individual to one of the subintervals of the entire dosage according to his/her baseline covariates under the estimated I2DR.

Usage

  opt.dose(X,I2DR)

Arguments

X

The patient’s baseline covariates, coule be a matrix, including continous or discrete covariates.

I2DR

The Individualized Interval-valued Dose Rule found by the function "JQL" or "RJQL".

Value
