forecasting

Maybe I'm missing a setting, but there currently seems to be no inbuilt in way to enable legends for the plot functions. Would it be possible to add this feature? Many thanks.

The extension guidelines should mention get_params, set_params, and that they may have to be manually reimplemented on complex composites where components are not directly arguments of the constructor.

E.g., with a "todo" and commented code which explains when and how to implement get_params, set_params (and with which signature.

Description

(A clear and concise description of what the feature is.)

• util.cumsum implementation https://github.com/awslabs/gluon-ts/blob/master/src/gluonts/mx/util.py#L326 does not scale under mx.ndarray
• cumsum is 2-5 times slower than nd.cumsum under both mx.sym and mx.ndarray, and even fails for large 4-dim input

Sample test

Code

# import ...
def test_

In order to create an outlier detection with Prophet, i need the full dataframe that's return Prophet

Describe proposed solution
Remove the hardcoded ["yhat"] from Prophet.predict add a variable asking to return just yhat or all the predictions: 'yhat_lower', 'yhat_upper', etc..

1. The README.md does not mention or link to ReadTheDocs documentation. It would be great if it did.

2. The Getting Started page does mention ReadTheDocs documentation but does not link to it. We should add this [link](https://flow-forecast.readthedocs.io/en/la

While sales forecasting, it is necessary that the model is given the input about the promotions, special events that are taken care of in the prophet model as the holiday effect. Does orbit support this feature?
