Hi everybody, Working with interval censored data using S+, I often use the survival analysis' functions kaplanMeier() and censorReg(). Does anybody know, whether these functions exist in R, too? Thanks in advance for any answer! Saludos, Klaus. ---------------------------------------------------- Klaus Langohr Departament d?Estad?stica i Investigaci? Operativa Universitat Polit?cnica de

...andt's webpage, http://www.psci.unt.edu/~brandt/pests/pests.htm. He said he is working out R versions as well! Jake Bowers pointed me to Jim Lindsey's packages for Nonlinear Regression and Repeated Measurements which has some functions which appear very promising: http://alpha.luc.ac.be/~lucp0753/rcode.html Thomas Lumley pointed out that instead of NB, one can get a Poisson-Normal mixture out of this by changing the assumption on the error term. He pointed me at some articles that are exactly on point - Zeger (Biometrika 1988, pp621-629) gives an estimation procedure for a time series co...

Hi all, I am a PhD student in sociology, studying in Essen, Germany. I am doing an empirical research with data on three (hierarchical) levels: Individuals within schools within regions. The data are very sparse with a lot of schools containing only one individual. In addition the dependent variable is dichotomous, so that a logistic regression would be appropriate. There are independent variables

Hi there fellow R-users, Can anyone tell me if there exits an R package that deals with serial correlation in the residuals of an lm model. Perhaps, using the Cochrane Orcutt or Praise Wilson methods? Thanks, Wayne Dr Wayne R.

Greetings- I have some data on which I need to do something like a Hierarchical Linear Model (please bear with me, I'm only learning the technique so I don't know yet if my language is correct). Essentially I'm analyzing data at two levels simultaneously; data are about individuals an organizations of which they are members. Can someone point me toward an appropriate package in R?
