In OTRselect: Variable Selection for Optimal Treatment Decision

Mean Response or Restricted Mean Response Given a Treatment Regime

Description

Estimates the mean response given a treatment regime if data is uncensored. If data is censored, estimates the restricted mean response given a treatment regime.

Usage

Qhat(y, a, g, wgt = NULL)

Arguments

y	vector of responses. Note if logY = TRUE in censored, this value should also be the logarithm.
a	vector of treatments received.
g	vector of the given treatment regime.
wgt	weights to be used if response is censored.

Value

Returns the estimated mean response or restricted mean response.
