ds.mediationTest.RdThis function is similar to the R function mediation.test that is included
in the bda package. The function computes statistics and p-values for three versions of
Sobel mediation test: Sobel test, Aroian test and Goodman test.
ds.mediationTest(mv = NULL, iv = NULL, dv = NULL, datasources = NULL)a string character, the name of the mediator variable
a string character, the name of the independent variable
a string character, the name of the dependent variable
a list of DSConnection-class
objects obtained after login. If the datasources argument is not specified
the default set of connections will be used: see datashield.connections_default.
A table showing the values of the test statistics (z-values) and the corresponding p-values for the Sobel, Aroian and Goodman tests for each study separately.
To test whether a mediator carries the influence on an independent variable to a dependent variable. Missing values will be automatically excluded with a warning.
