I am trying to compile the R-dev sources on WinXP using mingw 3.1.0-1 and fpTeX 0.7. In the past I have been able to build the sources fine but now I receive an error in the process that I havent seen reported on the list before. Everything works fine until I get to 'make docs'. I now get the message below while building the R-admin manual (refman.pdf builds fine) and the make process

First of all, I should have gone to bed a long time, so please be forgiving with regards to what will follow :) So I''ve been working all day on a rails project that needs to go out soon, and I thought I would try to refactor a has_many relationship to a has_and_belongs_to_many relationship (using has_many :through). However, I then realized that I would loose a lot of the simple beauty

Hi, I have an application under Access that is running dead slow. I've done some testing and it appears that Access really likes to use OPLOCKS which of course Samba does not support. Is there any work underway to get Samba to support OPLOCKS? I know they are difficult to implement but I'm faced with a decisions now to buy an NT box (Ugh!) or do a lot of messing around to get this

Two bugs in liboggz mux ordering bit me tonight. These are patches against current GIT, I'll apply if no one else volunteers, but I'd prefer a quick review. I'm surprised they'd not been caught, as it was causing oggz-sort/oggz-merge to mis-mux potentially all files containing theora (the frame->time calculation accounted for stream version backwards, and the result was always

Hola, espero ser clara en el mensaje ya que es la primera vez que recurro a este tipo de ayudas, explico mi duda: Tengo un dataset con 4505 observaciones en el que la variable dependiente son presencias (n=97 y clasificadas como 1) y ausencias (n=4408 y clasificadas como 0). Mi primer paso fue realizar un GLM con una muestra compensada de ausencias y presencias para la variable dependiente, es

Buenas tardes, Estoy estimando un modelo binomial negativo de ceros inflados (ZINB) utilizando el comando zeroinfl() del paquete pscl. Al ejecutarlo me da el siguiente aviso: Warning: glm.fit: fitted probabilities numerically 0 or 1 occurred ¿Sabéis que significa y si puedo usar el modelo aún con ese aviso? ¿Los coeficientes son fiables? Muchas gracias, Miriam

Sin embargo, al incluir otro tipo de variables independientes no me da ese aviso, dejando la misma variable dependiente. ¿Cómo podría utilizar stan/rstan de forma sencilla para diagnosticar el modelo? Muchas gracias El Lun, 9 de Abril de
