createEdgewiseIdentifier: Create an edgewise identification function

In SEMID: Identifiability of Linear Structural Equation Models

Create an edgewise identification function

Description

A helper function for edgewiseIdentifyStep, creates an identifier function based on its given parameters. This created identifier function will identify the directed edges from 'targets' to 'node.'

Usage

createEdgewiseIdentifier(
  idFunc,
  sources,
  targets,
  node,
  solvedNodeParents,
  sourceParentsToRemove
)

Arguments

idFunc	identification of edge coefficients often requires that other edge coefficients already be identified. This argument should be a function that produces all such identifications. The newly created identifier function will return these identifications along with its own.
sources	the sources of the half-trek system.
targets	the targets of the half-trek system (these should be the parents of node).
node	the node for which all incoming edges are to be identified (the tails of which are targets).
solvedNodeParents	the parents of node that have been solved
sourceParentsToRemove	a list of the parents of the sources that should have their edge to their respect source removed.

Value

an identification function
