<@U0E6TGXUN> i am not 100% certain I follow, but Sequences are supported too. If you can show me pseudo code of what your alternate thinking is, that might be helpful. Some of these models are difficult to express in an integrated way with operational code, such as linear regression. But you can take the result and integrate it back Im sure in many cases.

But yes, you have to extract, transform, and flatMap your data in advance from your production model to use a lot of these statistical operators. Putting that result back into your production code is a separate matter i cannot imagine including in this library.
