tsibble

问题 Do you ever look back a your old questions and feel a bit embarrassed? I just did, and now I do. And I'll probably feel the same about this one at some point. I'm trying to move my forecasting work to fable . In the process I'm trying to use a tsibble . Previously with a ts object I just set the start year and frequency. Now the tsibble is looking for a date object. However I have data which is biannual (fall and spring semester). And the variable is irregular (which I would like to keep).

问题 I am trying to fit some time series using the R packages tsibble and fable , the still-under-construction replacement for the redoubtable Rob Hyndman's forecast package. The series are all combined into one tsibble, which I then fit with ARIMA, a function which replaces, among other things, forecast::auto.arima . I use map_at , first to iterate over all the elements except the Date , and then again to extract the model information from the models that have been fit to each series using
