@brdick Not yet, unfortunately. We're working on making that available ASAP as it is a common request in the feedback we're having. In our next release (1-2 weeks) we're hoping to make it available.

@kkdub We can't go deep into details on how the algorithm works, but at it's core we are using SARIMA models (so no ML/deep learning approach, but statistical methods) combined with a lot of previous analysis and pre-processing of the input data to find out sane parameters for the forecast. Along with this there is some manual optimization done previously by us on various datasets, to figure out optimal parameters for all the processing steps. As far as specificity goes, we can't make claims that it is completely generic - that would be quite a feat. We started by tailoring it to a specific use-case - energy consumption forecast - but soon figured out that the resulting models were not really reflecting energy consumption patterns, but human-driven patterns, that tend to follow similar trends and seasonalities whatever the domain is. So right now we're opening it up for testing on similar human-centric domains - usage of appliances/tools, website visits, retail metrics... obviously it won't work equally well on every domain, but that's what we are here to figure out. Sample size: that depends heavily on the nature of the data, granularity and seasonality - we tended to find good results while testing by supplying it with at least 3 seasonal repetitions to forecast the next one (eg. three weeks of data to forecast the next one) but of course that would need to change if, for example, we want to take into account monthly/yearly fluctuations. It ends up being a matter of testing it with the available data and evaluating the results.
