fluctuateQ1 function

fluctuateQ1

Function called internally by drtmle to perform the first fluctuation of the initial estimator of Q (i.e., solves the original EIF estimating eqn)

fluctuateQ1(Y, A, W, DeltaA, DeltaY, Qn, gn, a_0, coefTol = 1000)

Arguments

• Y: The outcome
• A: The treatment
• W: The covariates
• DeltaA: Indicator of missing treatment (assumed to be equal to 0 if missing 1 if observed)
• DeltaY: Indicator of missing outcome (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
• a_0: A list of fixed treatment values
• coefTol: A tolerance level on the magnitude of the coefficient that flags the result as potentially the result of numeric instability.
