equivalence: Identify candidates of equivalent models
In lava: Latent Variable Models

Identifies candidates of equivalent models

1	equivalence(x, rel, tol = 0.001, k = 1, omitrel = TRUE, ...)

`x`	`lvmfit`-object
`rel`	Formula or character-vector specifying two variables to omit from the model and subsequently search for possible equivalent models
`tol`	Define two models as empirical equivalent if the absolute difference in score test is less than `tol`
`k`	Number of parameters to test simultaneously. For `equivalence` the number of additional associations to be added instead of `rel`.
`omitrel`	if `k` greater than 1, this boolean defines wether to omit candidates containing `rel` from the output
`...`	Additional arguments to be passed to the low level functions
