Estimate a mediation model based on EM covariance matrix
bmem.em(x, ram, indirect, v, robust = FALSE,
varphi = 0.1, st= "i", moment = FALSE,
max_it = 500, ...)
A data set
RAM path for the mediaiton model
A vector of indirect effec
Indices of variables used in the mediation model. If omitted, all variables are used.
Roubst method
Percent of data to be downweighted
Starting values
Select mean structure or covariance analysis. moment=FALSE, covariance analysis. moment=TRUE, mean and covariance analysis.
Maximum number of iterations in EM
Other options for sem function can be used.
