fluctuateQ2 {drtmle}

fluctuateQ2

Description

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

Usage

fluctuateQ2(Y, A, W, DeltaY, DeltaA, Qn, gn, grn, a_0, reduction,
  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)

Qn

A list of outcome regression estimates evaluated on observed data

gn

A list of propensity regression estimates evaluated on observed data

grn

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

a_0

A list of fixed treatment values

reduction

A character indicating what reduced dimension regression was used.

coefTol

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