Dear all, I generated a covariance matrix and I would like to generate a 1D plot of the data that auto-correlate. any suggestions? Thanks, Marcelo -- Marcelo Andrade de Lima UNIFESP - Universidade Federal de São Paulo Departamento de Bioquímica Disciplina de Biologia Molecular Rua Três de Maio 100, 4 andar - Vila Clementino, 04044-020 Lab +55 11 55764438 R.1188 Cell +55 11 92725274

Hi everybody, I am trying to generate two random walks with an specific correlation, for example, two random walks of 200 time steps with a correlation 0.7. I built the random walks with: x<-cumsum(rnorm(200, mean=0,sd=1)) y<-cumsum(rnorm(200, mean=0,sd=1)) but I don't know how to fix the correlation between them. With white noise is easy to fix the correlation using the function

Hello, I'm trying to write the following matlab code into R: N = zeros(n-1); for i=2:(n-1) N(1,i) = 1/(pi * (i-1)); end for i=2:(n-2) for j=i:(n-1) N(i,j) = N(i-1,j-1); end; end for i=2:(n-1) end for j=1:i N(i,j) = -N(j,i); end; any suggestions? Thanks can i just add the following line to my calculation N=1/(pi*(i-1) -- Marcelo Andrade de Lima UNIFESP - Universidade Federal

Dear List I just downloaded and installed R 2.12.0 and then installed R Commander . First it got RCmdr and Car, and then suggested for other packages for utilizing the full functionality- I clicked yes! I got 140 packages installed!!! Cran Mirror was UCLA... Here is the list. Is this intentional- I can see some packages like snow and multicore which are desirable but quite optional.(see list

Hi, Created a covariance matrix and i would like to add a diagonal line to the plot, any suggestions?

Hola, ¿qué tal? Victor Peinado (http://nlp.uned.es/~victor/) y yo estamos organizando un grupo de lectura. Junto con quienes se nos sumen, vamos a ir leyendo el libro "Analyzing Linguistic Data: A practical introduction to Statistics" (http://www.ualberta.ca/~baayen/publications/baayenCUPstats.pdf), que trata de: - R (instalación, gráficos, etc.) - Métodos estadísticos con R (modelos

hola! podrian ayudarme con esto: Genere 1000 muestras aleatorias de tamaño n=10 de una población normal con media =2,5 y desviación 0,16. Con cada una de las muestras construya un intervalo de confianza al 95% para la media y para la varianza. Cuente que porcentaje de los 1000 intervalos atrapan la verdadera media y la verdadera varianza poblacional respectivamente. Comente los resultados
