updateMu: Update 'mu', the Fitted Mean Response
Description
Updates the mean vector \(\mu\) given the linear predictor
\(\gamma\). Evaluate the residuals and the weighted sum of squared
residuals.
Usage
updateMu(respM, gamma, …)
Arguments
respM
a response module, see the
'>respModule
class.
gamma
the value of the linear predictor before adding the offset
…
potentially further arguments used in methods; not used
currently.
Methods
signature(respM = "glmRespMod", gamma = "numeric")

signature(respM = "nglmRespMod", gamma = "numeric")
..
signature(respM = "nlsRespMod", gamma = "numeric")
..
signature(respM = "respModule", gamma = "numeric")
..
Details
Note that the offset is added to the linear predictor before
calculating mu.
The sqrtXwt matrix can be updated but the sqrtrwt should not be in
that the weighted sum of squared residuals should be calculated
relative to fixed weights. Reweighting is done in a separate call.
