Description

hgam is used to fit high-dimensional generalized additive models.

Usage

1
2
hgam(formula, data = NULL, weights, model = LinReg(), 
     nknots = 20, lambda1 = 2, lambda2 = 3, ...)

Arguments

formula

an object of class formula (or one that can be coerced to that class): a symbolic description of the model to be fitted.

data

a data frame.

weights

vector of weights.

model

an object of class grpl.model implementing the negative log-likelihood, gradient, hessian etc. See the documentation of grpl.model for more details.

nknots

number of knots.

lambda1

grouplasso penalty term.

lambda2

smoothing penalty term.

...

ignored.

Value

hgam returns an object of class hgam:

y

response

x

covariables

Btilde

model matrix

coef

coefficients

Btildenew

function to set up the model matrix for (new) data
