Por favor agradecería sus respuesta Saludos Cordiales Valeska Yaitul Yaitul. [[alternative HTML version deleted]]

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.

...doesn't make a difference, but working with an epidemiologist, Marilia Carvalho, we wanted to map the standardised residuals of a quasipoisson null model of cases offset by log(pop.at.risk), and rstandard.glm() seemed to compress the values more than we'd have expected. Her colleague: "Valeska (L. Andreozzi) says that she has already noticed that, and as McCullagh & Nelder (2nd ed, pg 397) says, the dispersion is inside the sqrt". (That's the way I read 12.5 on p. 397 too). I can't see that summary(model)$dispersion has already been subject to sqrt() in sum(object$wei...
