\usage{
unstable_params(seminr_model, deviant_groups, params = "path_coef")
}
\arguments{
\item{seminr_model}{An estimated SEMinR model.}

\item{deviant_groups}{A `coa_dtree` object from [deviance_tree()], or a
named list of integer vectors of case indices. When a `coa_dtree` is
passed, the `$deviant_groups` element is extracted automatically.}

\item{params}{Character vector of model parameters to diff
(default `"path_coef"`).}
}
\value{
An object of class `coa_unstable`: a named list (one entry per group)
  each containing `cases` and `param_diffs`.
}
\description{
Identifies unstable model parameters by removing each deviant group
and re-estimating the model, then computing the difference in specified
parameters.
