Hello all, could you tell where is an example of metropolis hasting? Thank you! Tania Sent from my iPod

Hi R community, I have some data set and construct the likelihood as follows likelihood <- function(alpha,beta){ lh<-1 d<-0 p<-0 k<-NULL data<-read.table("epidemic.txt",header = TRUE) attach(data, warn.conflicts = F) k <-which(inftime==1) d <- (sqrt((x-x[k])^2+(y-y[k])^2))^(-beta) p<-1 - exp(-alpha*d) for(i in 1:100){

Hi all, So I have two tables: - apps (short for applicants) has_and_belongs_to_many :locations - locations has_and_belongs_to_many :apps In my system, a user searches for applicants by the locations to which they are associated, by using a dropdown menu that includes the names of locations (and sends to the method that returns the results the id of the selected location). So, in the

Hi, I seem to have a key colour problem with a lattice barchart. The colours on my key rectangle don't match the colours on the barchart. Here is my data frame: "LandFill" "Ruminants" "United States (USA)" 7777.21428 5528.16 "France" 200.527083 1299.87 "Australia" 185.878368 2448.17 "Russian Federation" 1752.8334 2024.29

I have been trying to download the climstats package: https://r-forge.r-project.org/R/?group_id=861 but it doesn't seem to run on R 3.0.2 or 3.0.1 and the zipfile is empty. Does anyone know the status of this package or where I can download it.

Hello, My name is Ick Hoon Jin and I am Ph. D. student in Texas A & M Univ.. When I run the C embedded in R in the Linux system, I confront the following error after 6,000 iteration. By googling I found this error is from the problem in C. *** caught segfault *** address (nil), cause 'memory not mapped' My C code is following:

Hello, I would like to calculate the 95% confidence intervals for the estimates of a linear model and I just wanted to check that I am doing it correct. Is it just: Estimate + 1.95996*Std.Error to Estimate - 1.95996*Std.Error or is there another approach that doesn't assume a normal distrbution? Thanks. Apologies for my naiivity Dan --

The background: I'm trying to fit a Poisson-lognormal distrbutuion to some data. This is a way of modelling species abundances: N ~ Pois(lam) log(lam) ~ N(mu, sigma2) The number of individuals are Poisson distributed with an abundance drawn from a log-normal distrbution. To fit this to data, I need to integrate out lam. In principle, I can do it this way: PLN1 <- function(lam, Count,

Dear Sir, I am beginner in using R. I am working on climate and like to plot spatial but I can't able to go ahead. I know it is too simply but not for me. Here is attached the data and my sample script. I am waiting R-users to solve my problem. Your help is valuable for me. Thank you. -- --------------------------------------------------- *Bedassa Regassa Cheneka* *Adama Science and

This is not related to R but I was hoping that someone could help me. I am reading the "Understanding the Metropolis Hastings Algorithm" paper from the American Statistician by Chip and Greenberg, 1995, Vol 49, No 4. Right at the beginning they explain the algorithm for basic acceptance rejection sampling in which you want to simulate a density from f(x) but it's not easy and you

In the past few days, I have been helping people from Ethiopia and from Kenya to get started with R. We have discovered that properly installed libraries (survival5 or mine) work and the online (with ?) help is available but they do not appear in the html help (under packages) with MS Windows. Only the libraries supplied with R appear there. This is not true with netscape under (Linux) X-Windows

Hola estimados miembros de la comunidad de R Tengo un conjunto de datos, donde tengo observaciones por países y por año. Una de las variables del dataframe es el nombre del país. Queremos dividir los países, que son países africanos de acuerdo a 5 regiones: norte de africa, africa del este, sur africa, etc Yo lo que he hecho ha sido crear vectores con el nombre de cada uno de los países en cada

Dear R-Help List, I'm trying to implement Firth's (1993) bias correction for log-linear models. Firth (1993) states that such a correction can be implemented by supplementing the data with a function of h_i, the diagonals from the hat matrix, but doesn't provide further details. I can see that for a saturated log-linear model, h_i=1 for all i, hence one just adds 1/2 to each count,

Pero eso es para crear variables binarias tipo 0-1 si el pais pertence a un determinado grupo. Lo que quiero es crear una variable de tipo factor con esos 5 niveles, sabiendo que tengo en el dataframe una variable llamada Country, con el nombre del pais.
