Graphical Model 7-dim IDA Data Examples
This data set contains a matrix containing information on seven gaussian variables and the corresonding DAG model.
data(gmI)
See gmG for more
The data was generated as indicated below. First, a random DAG was
generated, then samples were drawn from this model, strictly
speaking for gmI7 only.
The data sets are identical to those generated by
## Used to generate "gmI" set.seed(123) p <- 7 myDAG <- randomDAG(p, prob = 0.2) ## true DAG gmI <- list(x = rmvDAG(10000, myDAG, back.compatible=TRUE), g = myDAG) gmI7 <- list(x = rmvDAG( 8000, myDAG), g = myDAG)
data(gmI)
str(gmI, max=3)
stopifnot(identical(gmI $ g, gmI7 $ g))
if(dev.interactive()) { ## to save time in tests
