Hi,

When I run the code below, I am getting the following error.

vals <- c(3999, 4389, 4779, 5169, 5559, 8639, 6339, 6729, 7119, 7509, 7899, 8289, 8679, 9069, 9459)
data.frame(time=1:length(vals), edges=vals) %>%
tibble::as_tibble() %>%
tsibble::as_tsibble(index=time) %>%
fabletools::model(arima=fable::ARIMA(edges))

Error

A mable: 1 x 1

     arima
   <model>

1
Warning messages:
1: In max(which(abs(ma) > 1e-08)) :
no non-missing arguments to max; returning -Inf
2: 1 error encountered for arima
[1] argument must be coercible to non-negative integer

How to fix this?

Thanks,
Sevvandi
