df_netKmax6


Simulated dataset containing 3 measured i.i.d. baseline covariates (<code>W1</code>, <code>W2</code>, <code>W3</code>), dependent binary exposure (<code>A</code>)
 and dependent binary binary outcome (<code>Y</code>), along with a known network of friends encoded by strings on space separated
 friend IDs in <code>Net_str</code>.
 The baseline covariates (<code>W1</code>,<code>W2</code>,<code>W3</code>) were sampled as i.i.d.,
 while the exposure value of <code>A</code> for each observation <code>i</code> was sampled
 conditionally on the values of <code>i</code>'s baseline covariates (<code>W1[i]</code> <code>W2[i]</code>, <code>W3[i]</code>),
 as well as the baseline covariate values of <code>i</code>'s friends in <code>Net_str</code>.
 Similarly, the binary outcome <code>Y</code> for each observation was generated conditionally on <code>i</code>'s
 exposure and baseline covariates values in (<code>W1[i]</code>,<code>W2[i]</code>,<code>W3[i]</code>,<code>A[i]</code>),
 as well as the values of exposures and baseline covariates of <code>i</code>'s friends in <code>Net_str</code>.
 Individual variables are described below.

Estimation of average causal effects for single time point
interventions in network-dependent data (e.g., in the presence of spillover
and/or interference). Supports arbitrary interventions (static or
stochastic). Implemented estimation algorithms are the targeted maximum
likelihood estimation (TMLE), the inverse-probability-of-treatment (IPTW)
estimator and the parametric G-computation formula estimator. Asymptotically
correct influence-curve-based confidence intervals are constructed for the
TMLE and IPTW. The data are assumed to consist of rows of unit-specific
observations, each row i represented by variables (F.i,W.i,A.i,Y.i), where
F.i is a vector of friend IDs of unit i (i's network), W.i is a vector of
i's baseline covariates, A.i is i's exposure (can be binary, categorical or
continuous) and Y.i is i's binary outcome. Exposure A.i depends on
(multivariate) user-specified baseline summary measure(s) sW.i, where sW.i
is any function of i's baseline covariates W.i and the baseline covariates
of i's friends in F.i. Outcome Y.i depends on sW.i and (multivariate)
user-specified summary measure(s) sA.i, where sA.i is any function of i's
baseline covariates and exposure (W.i,A.i) and the baseline covariates and
exposures of i's friends. The summary measures are defined with functions
def.sW and def.sA. See ?'tmlenet-package' for a general overview.
