In mvaldora/SPPS:

Description

Estimates the mean of an outcome with missing values using the SPPS model

Usage

ipwmod(x, a, y, phi = expit, dphi = dexpit, phiinv = expitinv,
  type = 1, estim.method = "ML")

Arguments

x	A matrix of covariates of dimension n x p
a	A vector a of 0s and 1s of dimension n
y	A vector of responses or outcomes
phi	A function that maps the real line onto the interval (0,1)
dphi	The derivative of phi
phiinv	The inverse of phi
type	The type of IPW estimator to be used: type 1 , type 2 and type 3 combine SPPS with, respectively, IPW1, IPW2 and IPW3 in Lunceford and Davidian(2004)
estim.method	The estimation method to be used for estimating the parameters "ML" (default) or "LS"

Value

a list containing the estimate of the mean and the estimators of beta and epsilon
