LatentDigraph: Construct a LatentDigraph object

In SEMID: Identifiability of Linear Structural Equation Models

Construct a LatentDigraph object

Description

Creates an object representing a latent factor graph. The methods that are currently available to be used on the latent factor graph include

1. numObserved

2. numLatents

3. numNodes

4. toIn

5. toEx

6. L

7. observedNodes

8. latentNodes

9. parents

10. children

11. ancestors

12. descendants

13. trFrom

14. getTrekSystem

15. inducedSubgraph

16. stronglyConnectedComponent

17. plot

18. observedParents

19. getMixedGraph

see the individual function documentation for more information.

Usage

LatentDigraph(L = matrix(0,1,1),
                     observedNodes = seq(1, length = nrow(L)),
                     latentNodes = integer(0))

Arguments

L	see graphID for the appropriate form of L.
observedNodes	a vector of positive integers representing the vertex numbers of the observed nodes. These will correspond, in order, to the first length(observedNodes) rows of L.
latentNodes	a vector of positive integers representing the vertex numbers of the latent nodes. These will correspond, in order, to the last length(latentNodes) rows of L.

Value

An object representing the LatentDigraph
