create_node_list: Create a node list specification

Description

Creates a node list specification that is used by the provided estimators. create_node_list() is not explicitly called by the analyst, rather it is provided so the analyst can confirm how estimators will use variables before actually performing the estimation procedure.

Usage

create_node_list(trt, tau, time_vary = NULL, baseline = NULL, k = Inf)

Value

A list of lists. Each sub-list is the same length of the time_vary parameter with the variables to be used for estimation at that given time point for either the treatment mechanism or outcome regression.

Arguments

trt

A vector of column names of treatment variables.

tau

The number of time points of observation, excluding the final outcome.

time_vary

A list of length tau with the column names for new time_vary to be introduced at each time point. The list should be ordered following the time ordering of the model.

baseline

An optional vector of columns names for baseline covariates to be included for adjustment at every timepoint.

k

An integer specifying how previous time points should be used for estimation at the given time point. Default is Inf, all time points.

Examples

if (FALSE) {
a <- c("A_1", "A_2", "A_3", "A_4")
bs <- c("W_1", "W_2")
time_vary <- list(c("L_1"), c("L_2"), c("L_3"), c("L_4"))

# assuming no Markov property
create_node_list(a, 4, time_vary, bs, k = Inf)
}
