Estimating Equations for rpsftm()

Description

Calculates the Estimating Equation to be solved in RPSFTM models

Usage

est_eqn(psi, data, formula, target = 0, test = "survdiff", autoswitch, ...)

Arguments

psi	the parameter that measures how more rapidly the lifetime is expended under treatment
data	the data set that contains the variables. Must contain columns named: time, censor_time,rx, arm. Optionally a column named: treat_modifier
formula	a formula object of covariates to adjust for: ~strata(A)+B*C
target	the value to subtract off from the z-statistic
test	the survival regression function to calculate the z-statistic: survdiff, coxph, survreg
autoswitch	a logical to autodetect cases of no switching. If TRUE, then if all observations in an arm have perfect compliance then recensoring is not applied in that arm. If FALSE the recensoring is applied regardless of perfect compliance.
...	arguments to supply to the test function.

Value

A scalar value of the estimating equation: the z-statistics from a test minus a target value
