fluctuateG {drtmle}

fluctuateG

Description

Function called internally by drtmle to perform the fluctuation of the initial estimator of g (i.e., solves the new estimating eqn that results from misspecification of Q)

Usage

fluctuateG(Y, A, W, DeltaY, DeltaA, a_0, gn, Qrn, tolg, coefTol = 1000)

Arguments

Y

The outcome

A

The treatment

W

The covariates

DeltaY

Indicator of missing outcome (assumed to be equal to 0 if missing 1 if observed)

DeltaA

Indicator of missing treatment (assumed to be equal to 0 if missing 1 if observed)

a_0

A list of fixed treatment values

gn

A list of propensity regression estimates evaluated on observed data

Qrn

A list of reduced-dimension regression estimates evaluated on observed data

tolg

The lower bound on propensity score estimates

coefTol

A tolerance level on the magnitude of the coefficient that flags the result as potentially the result of numeric instability.
