Simple minded polynomial regression.

`polyreg(x, y, w, degree = 1, monomial = FALSE, …)`

x

predictor matrix.

y

response matrix.

w

optional (positive) weights.

degree

total degree of polynomial basis (default is 1).

monomial

If `TRUE`

a monomial basis is used (no cross
terms). Default is `FALSE`

.

…

currently not used.

A polynomial regression fit, containing the essential ingredients for
its `predict`

method.
