PAL.control: Control parameters for penalized A-learning

Description

Parameters that control fitting of penalized A-learning.

Usage

PAL.control(pi1.est = NULL, pi2.est = NULL, h1.est = NULL, h2.est = NULL, kappa = NULL, 
  penalty = 'SCAD')

Arguments

pi1.est

Estimated propentisy score at the first stage. By default, a penalized logistic regression model is fitted to estimate the propensity score.

pi2.est

Estimated propentisy score at the second stage. By default, a penalized logistic regression model is fitted to estimate the propensity score.

h1.est

Estimated baseline function at the first stage. By default, a penalized linear regression model is fitted to estimate the baseline function.

h2.est

Estimated baseline function at the second stage. By default, a penalized linear regression model is fitted to estimate the baseline function.

kappa

The model complexity penalty used in the information criteria. By default, \(kappa=1\) if BIC or CIC is used and \(kappa=4\) if VIC is used.

penalty

The penalty to be applied to the propensity score and baseline model. Either "MCP", "SCAD" (the default), or "lasso".

Value

A list with the arguments specified.

n <- 200
p <- 200
X <- matrix(rnorm(n*p), nrow=n, ncol=p)
A <- rbinom(n, 1, 0.5)
CX <- (X[,1] + X[,2])
h <- 1 + X[,1] * X[,3]
Y <- h + A*CX + 0.5*rnorm(n)
result <- SAS(Y~X|A, pi1.est=0.5)
