data(data_parallel)
mod <-
"
m1 ~ a1 * x + c1 + c2
m2 ~ a2 * x + c1 + c2
y ~ b2 * m2 + b1 * m1 + x + c1 + c2
indirect1 := a1 * b1
indirect2 := a2 * b2
indirect := a1 * b1 + a2 * b2
"
fit <- sem(mod, data_parallel,
           meanstructure = TRUE, fixed.x = FALSE)
parameterEstimates(fit)[c(1, 4, 7, 8, 27:29), ]
