Positivity constraint for predictions

[candalfigomoro]

With greykite/silverkite, is it possible to set a positivity constraint for predictions? Something similar to the "Approach 5" you can find here for prophet: facebook/prophet#1668 (comment)

This is a common requirement for many business-related time series.

Thanks

Hi @candalfigomoro by positive constraint, did you mean to make the predictions always positive? You could specify "min_admissible_value" in "SimpleSilverkiteTemplate.custom" and all negative values will be masked with 0.
