Dear list, I would like to fit a negative binomial regression model as described in "Byers AL, Allore H, Gill TM, Peduzzi PN., Application of negative binomial modeling for discrete outcomes: a case study in aging research. J Clin Epidemiol. 2003 Jun;56(6):559-64" to my data in which the response is count data. There are also 10 predictors that are count data, and I have also 3 categorical and 2 continious predictors. There is overdispersion in the distribution of the response variable (mean=2.8, variance=28) as well a...

...My group at Novartis is looking for statisticians, bioinformaticians, or R programmers to support molecular diagnostics, with open positions in Cambridge MA, USA (priority) and in Basel Switzerland (possible). We do a range of data analyses across product lifecycle (research, tech dev, clin dev, market access) to support the development of prognostic and predictive diagnostics. And of course, our main computational platform is R (using Emacs / ESS / org-mode for workflow, SNOW and add-ons for computation, etc), on a mixture of Microsoft and Linux workstations and cl...

I am new to R, and I am trying to cut a continuous variable BMI into different categories and can't figure out how to use it. I would like to cut it into four groups: <20, 20-25, 25-30 and >= 30. I am having difficulty figuring the code for <20 and >=30? Please help. Thank you. -- View this message in context:
