Mort1Dsmooth_update: Update a 1D Penalized-Poisson Iteration

In MortalitySmooth: Smoothing and Forecasting Poisson Counts with P-Splines

Description

This is an internal function of package MortalitySmooth which update coefficients for penalized B-splines for a given smoothing parameter within the function Mort1Dsmooth.

Usage

Mort1Dsmooth_update(x, y, offset, wei, psi2, B, lambdaP, a) 

Arguments

x	vector for the abscissa of data.
y	vector of counts response.
offset	vector with an a priori known component (optional).
wei	an optional vector of weights to be used in the fitting process.
psi2	an overdispersion parameter used the quasi-likelihood approach.
B	B-splines basis.
lambdaP	penalty factor, included the smoothing parameter.
a	old coefficients.

Details

Internal function used for updating coefficients of the B-splines in 1D Poisson penalized B-splines model.

Value

A vector of updated coefficients
