AIPW_tmle class uses a fitted tmle or tmle3 object as input

Value

AIPW_tmle object

Details

Create an AIPW_tmle object that uses the estimated efficient influence function from a fitted tmle or tmle3 object

Constructor

AIPW$new(Y = NULL, A = NULL, tmle_fit = NULL, verbose = TRUE)

Constructor Arguments

ArgumentTypeDetails
YIntegerA vector of outcome (binary (0, 1) or continuous)
AIntegerA vector of binary exposure (0 or 1)
tmle_fitObjectA fitted tmle or tmle3 object
verboseLogicalWhether to print the result (Default = TRUE)

Public Variable Details

obs_est

This list extracts from the fitted tmle or tmle3 object. It includes propensity scores (p_score), counterfactual predictions (mu, mu1 & mu0) and efficient influence functions (aipw_eif1 & aipw_eif0)

g.plot

This plot is generated by ggplot2::geom_density

ip_weights.plot

This plot uses truncated propensity scores stratified by exposure status (ggplot2::geom_boxplot)
