Hello, I have a dataset concerning slugs. For each slug, the number of pumps per one time slot was counted. The number of pumps follows Bi(30, p) where p is very small, thus could be approximated by Poisson dist. (# of pumps is very often = 0) The slugs were observed during 12 time slots which are correlated in time as AR(1). The time slots are divided into two categories: Resting time

Hello. I''m creating my own RESTful blog app. I am wondering about creating post slugs. I think Wordpress creates a slug at post creation time and stores the string in the database, then uses that for URLs. I read about the acts_as_sluggable strategy (http:// agilewebdevelopment.com/plugins/acts_as_sluggable) but I don''t like having a number (the ID) in the URL. Any

I am not sure where I should even begin troubleshooting this. I know a little bit about Linux and am comfortable editing files and running commands however definitely not a Linux guru. I have ipkg already installed on the QNAP. I know absolutely nothing about ruby on rails. Thanks for any help. For those that are not familiar with a QNAP, ipkg is the same as apt-get or yum in some Linux

I have a problem in where i generate m independent draws from a binomial distribution, say draw1 = rbinom( m , size.a, prob.a ) then I need to use each draw to generate a beta distribution. So, like using a beta prior, binomial likelihood, and obtain beta posterior, m many times. I have not found out a way to vectorize draws from a beta distribution, so I have an explicit for loop

Hi Hadley and everyone, here's a patch for ggplot2 that fixes the behavior of opts(legend.position={left,top,bottom}). If you try the following code in an unmodified ggplot2 options(warn = -1) suppressPackageStartupMessages(library("ggplot2")) data <- data.frame( x = c(1, 2, 3, 4, 5, 6), y = c(2, 3, 4, 3, 4, 5), colour = c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE))
