IWLS vs direct ML estimation
Hi,
I am thinking about IWLS vs ML estimation. When I use glm() for a
2-parameter distribution (e.g., Weibull), I can otain the MLE of scale
parameter given shape parameter through IWLS. Because this scale parameter
usually converges to the MLE.
In this point, I am wondering:
i) can you say that the direct MLE, which is ob...

glm fitting routine and convergence
...) in c and I've been
using glm to check my results. I came across a data set that has a very
high condition number (the data matrix transpose the data matrix) that when
running my solver does not converge, but the same data set with glm was
converging ( I love R :) ). I noticed that glm using IWLS to solve the MLE
problem I also noticed that the results from glm suggest that glm checks
for complete separation for variables. Besides this check for variable
separation is glm doing anything else besides a straight implementation to
IWLS that would allow it to converge for a near ill-posed data...

maximum likelihood method to fit a model
Dear R users,
I use the glm() function to fit a generalized linear model with gamma distribution function and log link.
I have read in the help page that the default method used by R is "glm.fit" (iteratively reweighted least squares, IWLS).
Is it possible to use maximum likelihood method?
Thanks

glm with Newton Raphson
Hi,
Does anyone know if there is a function to find the maximum likelihood
estimates of glm using Newton Raphson metodology instead of using IWLS.
Thanks

Firths bias correction for log-linear models
...m the function hatvalues. For logistic
regression, this can be performed by splitting up each observation into response
and nonresponse, and using weights as described in Heinze, G. and Schemper, M.
(2002), but I'm unsure of how to implement the analogue for log-linear models. A
procedure using IWLS is described by Firth (1992) in Dodge and Whittaker (1992),
but this book isn't in the local library, and its $141+ on Amazon. I've tried
looking at the code in the logistf and brlr libraries, but I haven't had any

iwlwifi problem after Centos 8.2 update

At the beginning i though it was libvrtd but after stopping it gnome

I searched my log files and I saw alot of iwlwifi message.
I had to turn off wifi in order to stop high cpu usage.
Any ideas how to solve it?
Thanks in advance!

Pearson residuals (PR#1123)
...(NULL) (138.251.202.115)
I think there is a problem when computing Pearson residuals, in that they seem
to be computed at the raw residuals divided by the square root of the
corresponding diagonal element of the weight matrix W evaluated at the last step
of the iterative model fitting procedure (IWLS), instead of dividing by the
square root of the model variance. Here's an example of the weird effects it
produces:
> me <- c(1:100)/2
> y <- rpois(100,me)
> yglm <- glm(y~me-1, family=poisson(link="identity"))
> plot(fitted(yglm), residuals(yglm,type="resp...

No patch is needed, data.frame just doesn't work like that:

Algorithm used by glm, family=binomial?
Does anyone know what algorithm R uses in glm, family=binomial (i.e. a
logit model)?
I assume that it's in the source somewhere, but I wasn't able to find
it. I'd like to know
what file it's in (in a unix distribution of R).
Thanks for your help.

residuals in multinom
Hi,
is there a possibility to calculate the different "types" of residuals
directly using the multinom function from MASS as it is possible for the
functions gam, glm
using type="deviance" or "working" or "pearson" or "response"? I tried it
but got always the "response" type, I guess.
thanx

Modifying glm.fit() / execution path
Hello all,
I'm sure I'm missing something simple here, but I can't figure out how to
modify the glm.fit() function and then get R to use it (sort of). I'm doing
something along the lines of:
glm.fit<-edit(glm.fit) # add something trivial to the top of the glm.fit
function like: print("Hello world!")
#now have a modified glm.fit in position 1/.GlobalEnv
