I plan to use prophet for prediction. But when I fit a model I receive error. I use example from modeltime.resample:
library(dplyr)
library(lubridate)
library(parsnip)
library(rsample)
library(timetk)
library(modeltime)
m750 <- m4_monthly %>% filter(id == "M750")
splits <- initial_time_split(m750, prop = 0.8)
model_spec <- prophet_boost(
learn_rate = 0.1
) %>%
set_engine("prophet_xgboost")
model_fit <- model_spec %>%
fit(log(value) ~ date + as.numeric(date) + month(date, label = TRUE),
data = training(splits))
When I fit model I get
Error: CCTZ: Unrecognized timezone of the input vector: "GMT"
I try reinstall rstan and prophet packages, but error repeat.
