## Regression, especially Nonparametric Regression

*25 Sep 2014 11:57*

"Regression", in statistical jargon, is the problem of guessing the average level of some quantitative response variable from various predictor variables.

Linear regression is perhaps the single most common quantitative tool in
economics, sociology, and many other fields; it's certainly the most common use
of statistics. (Analysis of variance, arguably
more common in psychology and biology, is a disguised form of regression.)
While linear regression deserves *a* place in statistics, that place
should be nowhere near as large and prominent as it currently is. There are
very few situations where we actually have *scientific* support for
linear models. Fortunately, very flexible nonlinear regression methods now
exist, and from the user's point of view are just as easy as linear regression,
and at least as insightful. (Regression trees and additive models, in
particular, are just as interpretable.) At the very least, if you *do*
have a particular functional form in mind for the regression, linear or
otherwise, you should use a non-parametric regression to test the adequacy of
that form.

From a technical point of view, the main drawback of modern regression
methods is that their extra flexibility comes at the price of less "efficiency"
— estimates converge more slowly, so you have less precision for the same
amount of data. There are some situations where you'd prefer to have more
precise estimates from a bad model than less precise estimates from a model
which doesn't make systematic errors, but I don't think that's what most users
of linear regression are chosing to do; they're just taught to
type `lm`
rather
than `gam`.
In this day and age, though, I don't understand why not.

(Of course, for the statistician, a lot of the more flexible regression
methods look more or less like linear regression in some disguised form,
because fundamentally all it does is projection. So it's not crazy to make it
a foundational topic *for statisticians*. We should not, however, give
the rest of the world the impression that the hat matrix is the source of all
knowledge.)

The use of regression, linear or otherwise, for causal inference, rather than prediction, is a different, and far more sordid, story.
