object and returns a tibble
with exactly one row of model summaries.

Additional arguments. Not used. |
A one-row tibble with columns such as AIC
and BIC
.
The column converged
indicates whether the model converged or not. For
Mplus, this is TRUE
if the output contained the phrase "The model
estimation terminated normally". For mirt, this is equal to the output of
mirt::extract.mirt(x, "converged")
. For TAM, this is
NA
if no clear signs of non-convergence were observed. You are encouraged
to check any warnings or errors in any case.
iterations
is NA
for Mplus models since respective
information is not easily obtained from the output.
