Existence-of-seasonality narrative (HTML tag)

Uses IDS, M7, QS on original, and presence/absence of a SEATS seasonal component to provide a short textual assessment of seasonality for the best model.

Usage

sa_existence_card(res)

Arguments

res

Result of auto_seasonal_analysis().

Value

An htmltools tag representing the card.

Examples

# \donttest{
if (requireNamespace("seasonal", quietly = TRUE)) {
  res <- auto_seasonal_analysis(AirPassengers, max_specs = 3)
  sa_existence_card(res)
