Arguments

x

Vector for the abscissa of data

y

Vector of counts response

offset

Vector with an a priori known component (optional)

wei

psi2

An overdispersion parameter used the quasi-likelihood approach

B

B-splines basis

lambdaP

Penalty factor, included the smoothing parameter

a

Old coefficients

Value

• A vector of updated coefficients

Details
