The output from fitsem, this function lists all the connects in the fitted system by the two-stage penalized least squares (2SPLS) method (Chen, Zhang and Zhang, 2016).

1	getedges(fsObj)

fsObj

a result of a call to fitsem.

The output will list each connection in the fitted system in a row.

`target`	the indices of the target variables.
`source`	the indices of the source variables.
`weight`	the corresponding value in γ_k when the connect is included in the k-th structural equation.
