11/09/2022, 7:01 PMHey **@Kevin Kho**!
The

`fit`

method stores a `fitted_`

attribute containing the fitted models for each time series. Each fitted model is different. For example, the naive model stores the last time series observation, while Arima stores other objects required for forecasting. Currently, we do not have the functionality to use a different time series for forecasting. The `predict`

method only receives the horizon to forecast, so if the fitted model is saved, the forecasts produced by it will be the same each time `predict`

is called. We are working on adding the functionality to use new data. For the moment, we recommend using the forecast method.k

`fit()`

has one? How is it supplied to predict?Kevin Kho
