Description Usage Arguments Value Author(s) Examples
This function calculates probability associated with counterfactual collective outcome(s)
P(Y(a_j) = y) as a measure of influence of unit j
,
where a_j indicates the sole intervention of unit j
.

targetoutcome |
is a targeted couterfactual outcome of probability is in our interest, having different forms depending on the context of influence :
|
Avalues |
distinct treatment values of which maximum indicates intervention. Defaults to |
inputY |
a |
inputA |
a |
listC |
is either a matrix, list or
|
R.matrix |
a |
E.matrix |
a |
edgeinfo |
a list of matrix specifying additional directed edges (from confounders or treatment to the outcomes) information. Defaults to
|
n.obs |
the number of Gibbs samplers except for burn-in sample. |
n.burn |
the number of burn-in sample in Gibbs sampling. |
optim.method |
the method used in |
returns "noconvergence"
in case of failure to converence or a list with components :
|
|
|
the number of parameters estimated in conditional log-linear model. |
|
the estimated parameters. |
