A prophet model consists of terms which are additively or multiplicatively included in the model. Multiplicative terms are scaled proportionally to the estimated trend, while additive terms are not.

# S3 method for fbl_prophet
components(object, ...)

Arguments

object An estimated model. Unused.

Value

A fabletools::dable() containing estimated states.

Details

Extracting a prophet model's components using this function allows you to visualise the components in a similar way to prophet::prophet_plot_components().

Examples


# \donttest{
if (requireNamespace("tsibbledata")) {
library(tsibble)
beer_components <- tsibbledata::aus_production %>%
model(
prophet = prophet(Beer ~ season("year", 4, type = "multiplicative"))
) %>%
components()

beer_components

autoplot(beer_components)

library(ggplot2)
library(lubridate)
beer_components %>%
ggplot(aes(x = quarter(Quarter), y = year, group = year(Quarter))) +
geom_line()
