Tidy time series forecasting
I am trying to calculate the accuracy of a single point forecast for 2013. Model is trained on 2010-2012 data. It produces expected result, but also throws error: `[1] subscript...
Hello! Question: Will "Neural prophet" be available within `fable` workflow?
In `generate.TSLM()`, the variance of generated (non-bootstrapped) innovations is obtained as `x$sigma2 / x$df.residual`: https://github.com/tidyverts/fable/blob/a9404d8bdbd2990a49fffcc43257f8a6e9f9a5d3/R/lm.R#L331 Correct me if I'm wrong, but I believe that plain `x$sigma2` is in fact the...

Hi, When I run the code below, I am getting the following error. vals % tibble::as_tibble() %>% tsibble::as_tsibble(index=time) %>% fabletools::model(arima=fable::ARIMA(edges)) Error # A mable: 1 x 1 arima 1 Warning...
I am having difficulties to forecast ARIMA model with exogenous variables. Fitting of the model is not an issue, however when calling `forecast` on fitted ARIMA model with exogenous variables...
