Alexander Hess	015d304306	Add HorizontalSMAModel ... - the model applies a simple moving average on horizontal time series - refactor `db.Forecast.from_dataframe()` to correctly convert `float('NaN')` values into `None`; otherwise, SQLAlchemy complains	2021-02-02 12:40:53 +01:00
Alexander Hess	796fdc919c	Add Forecast.from_dataframe() constructor ... - this alternative constructor takes the `pd.DataFrame`s from the `*Model.predict()` methods and converts them into ORM models	2021-02-01 15:50:30 +01:00

Alexander Hess	f37d8adb9d	Add confidence intervals to Forecast model ... - add `.low80`, `.high80`, `.low95`, and `.high95` columns - add check contraints for the confidence intervals - rename the `.method` column into `.model` for consistency	2021-01-20 16:57:39 +01:00
