Significance test of an additive term

Description

Significance test of an additive term relying on the methodology in Wood (Biometrika 2013). It is extracted from a hidden function in the 'mgcv' package. The additive term is estimated using the product of a matrix <X> and a vector <p>.

Usage

testStat(p, X, V, rank = NULL, type = 0, res.df = -1)

Arguments

p

Vector of spline parameters used to estimate f(x)

X

(Centered) B-spline basis evaluated on a fine regular grid on the support of variable <x>

V

Posterior variance-covariance matrix of parameter <p>

rank

Effective dimension of <p>

type

0 value by default

res.df

-1 indicates that the scale is fixed (cf. ordinal response)

Value

Returns a list with following elements:
