Dear all,
I am currently using R 4.3.2 and the data I am working with is the
following:
ts_ingresos_reservas = ts(ingresos_reservaciones$RESERVACIONES, start =
c(1996,11), end = c(2024,4), frequency = 12)

26655500), tsp = c(1996.83333333333, 2024.25, 12), class = "ts")
Now that I have my time series data, I tried generating forecasts with the
following code:
ingresos_reservas_arimamod = auto.arima(ts_ingresos_reservas)
ingresos_reservas_arimafor = forecast(ingresos_reservas_arimamod, h =
151)
ingresos_reservas_holtwintersmod = HoltWinters(ts_ingresos_reservas)
ingresos_reservas_holtwintersfor =
forecast(ingresos_reservas_holtwintersmod, h = 151)
ingresos_reservas_etsmod = ets(ts_ingresos_reservas)
ingresos_reservas_etsfor = forecast(ingresos_reservas_etsmod, level
= c(90,99), h = 151)
ingresos_reservas_batsmod = bats(ts_ingresos_reservas)
ingresos_reservas_batsfor = forecast(ingresos_reservas_batsmod, level
= c(90,99), h = 151, robust = TRUE)
ingresos_reservas_tbatsmod = tbats(ts_ingresos_reservas)
ingresos_reservas_tbatsfor = forecast(ingresos_reservas_tbatsmod,
level = c(90,99), h = 151, robust = TRUE)
ingresos_reservas_nnetarmod = nnetar(ts_ingresos_reservas)
ingresos_reservas_nnetarfor = forecast(ingresos_reservas_nnetarmod,
PI = TRUE, h = 151, robust = TRUE)
This code used to work, but now, I keep getting the following error:
Error in UseMethod("forecast", object) :
no applicable method for 'forecast' applied to an object of class "ets"
Error in UseMethod("forecast", object) :
no applicable method for 'forecast' applied to an object of class "nnetar"
Error in UseMethod("forecast", object) :
no applicable method for 'forecast' applied to an object of class "bats"
Error in UseMethod("forecast", object) :
no applicable method for 'forecast' applied to an object of class "bats"
It seems like the forecast function is not working for these models
anymore. Any idea of how to solve this issue?
Kind regards,
Paul
