Mort1Dsmooth_update: 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.
lambdaP
penalty factor, included the smoothing parameter.
Value
A vector of updated coefficients
Details
Internal function used for updating coefficients of the B-splines in
1D Poisson penalized B-splines model.
