Extract standard deviations of random errors of continuous
equation of mnprobit
function.
# S3 method for mnprobit
sigma(object, use.fallback = TRUE, ..., regime = NULL)
Returns the estimates of standard deviations
of \(\varepsilon_{i}\).
If regime = r
then estimate of
\(\sqrt{Var(\varepsilon_{ri})}\) is returned.
object of class "mnprobit".
