has-intercept not yet implemented in fastmath

@daslu
Do you have used fastmath/OLS and looked at this question of "has-intercept" ?
Not sure, if there is something to change here

@behrica
Fastmath's lm model has an :intercept? option:
https://github.com/generateme/fastmath/blob/f5ffc6d/src/fastmath/ml/regression.clj#L291

• :intercept? - should intercept term be included, default: true

Yes, it is useful. We use it in our tutorials:
https://scicloj.github.io/noj/noj_book.linear_regression_intro.html#prediction-by-day-of-week
https://scicloj.github.io/tablemath/tablemath_book.reference.html#examples-5

Or maybe I did not understand the question?

What do you mean by threshold?

I wonder if I still need to implement something.
Not sure why I created this issue.
