mediate
returns an object of class "mediate
",
"mediate.tsls
", a list that contains the components listed below.
The function summary
can be used to obtain a table of the results.
d1point estimate for average causal mediation effects.
d1.ciconfidence intervals for average causal mediation
effect. The confidence level is set at the value specified in
'conf.level'.
z0point estimates for average direct effect.
z0.ciconfidence intervals for average direct effect.
z0.ptwo-sided p-values for average causal direct effect.
n0the "proportions mediated", or the size of the average causal
mediation effect relative to the total effect.
n0.ciconfidence intervals for the proportion mediated.
n0.ptwo-sided p-values for proportion mediated.
tau.coefpoint estimate for total effect.
tau.ciconfidence interval for total effect.
tau.ptwo-sided p-values for total effect.
bootlogical, the boot
argument used.
treata character string indicating the name of the 'treat' variable
used.
mediatora character string indicating the name of the 'mediator'
variable used.
INTa logical value indicating whether the model specification
allows the effects to differ between the treatment and control conditions.
conf.levelthe confidence level used.
model.ythe outcome model used.
model.mthe mediator model used.
nobsnumber of observations in the model frame for 'model.m' and
'model.y'. May differ from the numbers in the original models input to
'mediate' if 'dropobs' was 'TRUE'.
clusterthe clusters used.
