Organize namespaces in such a way to minimize dependencies
This might be a very fringe concern, but for big apps any additional dependencies are a pain. It would be very nice if namespaces were organised in such a way that you could control what dependencies you have to pull in (via lein's :exclude). Or at least (since what's proposed would be a breaking change) if this is something that the project is mindful of going forward.
Happy do to a PR for this, but it's something I feel should be discussed first.
I'm going to go out on a limb: is this request driven by the recent addition of Apache Commons Math3 in kixi.core? If so, I support moving LOESS to a separate namespace. It's one of only a few functions in core which return a model rather than scalar statistics (the others being simple regression models), and perhaps all could be moved together since they're semantically related.
Let me know if this is what you had in mind, or if not then concretely what you'd prefer instead. No need to provide a PR yet.
Mostly, yes; and also as something to keep in mind for the future. Doubtless there will be other algorithms we'll be wanting to add in the future, but it would be a shame to sacrifice the super-lightweight nature of kixi for it.
As a new user I suspect I am hitting this issue when attempting to use LOESS. I have project.clj dependencies
[kixi/stats "0.4.3"]
[org.apache.commons/commons-math3 "3.5"]
but I get
(require '[kixi.stats.core :refer [locally-weighted-regression]])
IllegalAccessError locally-weighted-regression does not exist clojure.core/refer (core.clj:4119)
@gmp26 Hi Mike, apologies LOESS has been added since the latest official release. If you update the kixi/stats dependency to "0.4.4-SNAPSHOT" you'll be able to use the locally-weighted-regression function in its current location.
@henrygarner Many thanks Henry. I'd tried 0.4.4 but hadn't noticed it was a snapshot release.
I suspect this can be closed now, as there is no longer a commons-math dep?
