Mort1Dsmooth.update {MortalitySmooth}R Documentation

Update a 1D Penalized-Poisson Iteration

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
