Returns a table of parameters with columns corresponding to freely estimated parameters and rows corresponding to nodes in the tree.
parameters(tree, leafs.only = TRUE)A SEMtree object obtained from semtree
Default = TRUE. Only the terminal nodes (leafs) are
printed. If set to FALSE, all node parameters are written to the
data.frame.
Returns a data.frame with rows for parameters and columns for
terminal nodes.
The row names of the resulting data frame correspond to internal node ids
and the column names correspond to parameters in the SEM. Standard errors of
the estimates can be obtained from parameters.
