Produces a small summary table for nonlinear time-series models such as TVAR and LSTAR, focusing on model status and AIC.
summarise_tvarstar_posthoc(tsdyn_res)A data frame with one row per model and columns:
model: "TVAR", "LSTAR_I", "LSTAR_C".
status: model class string or NA.
aic: numeric AIC value or NA.
A list of model objects, typically with elements
$TVAR, $LSTAR_I, $LSTAR_C, as returned by
a fitting routine based on the tsDyn package.
For each of the three models (TVAR, LSTAR for I, LSTAR for C), the function extracts:
A textual status (class names of the object).
The AIC, if stats::AIC() can be computed.
If tsdyn_res is NULL, default rows with NA
values are returned.
