[R] About MC simulation of AR1 model in R

I want to run MC simulation of AR1(auto-regression) matrix in R, which would be as residuals in linear mixed model. AR1 matrix with the following character: ��r,��c is the auto-correlation parameter in the row and column direction. And I wrote one function in R ( under following). But I run

Re: [R] Fitting data using Generalized Pareto Distribution

Hello, Why quantile(train, 0.9) ? If you use quantile(train) it seems to fit the data much better. You haven't posted a data example so I've made up one. library(eva) # needed for rgpd() library(extRemes) set.seed(1) train <- rgpd(1e3, scale = 0.9, shape = -0.4) thresh90 <-

Was about to reply just to sender but thought there were good byproducts of this so, to all ... Many thanks Dr. Winsemius, and apologies for the HTML: tired sloppiness. My bad. Aha. For the first time I can really see a logic for dataFrame[['variable']] -- thanks for that. I will have to

Re: [R] Fitting data using Generalized Pareto Distribution

Let the train be the data set consisting of numbers that I need to fit. Code is as follows: library(extRemes) thresh90 <- quantile(train, 0.90) model<-fevd(train,threshold =thresh90,type="GP") Model returns the following : Negative Log-Likelihood Value: 317.7561 Estimated parameters:

Hello, Please provide us with a reproducible example. A data exampla would be nice and some working code, the code you are using to fit the data. Rui Barradas Em 27-11-2016 15:04, TicoR escreveu: I am trying to fit some data using Generalized Pareto Distribution in R using extRemes

[R] In praise of "options(warnPartialMatchDollar = TRUE)"

I am just posting this to the list because someone else may one day waste an hour or so because s/he has unknowingly hit a partial match failure using "$". It's my folly that I did but I am surprised that options(warnPartialMatchDollar = TRUE) isn't the default setting. Here's a bit of

I am not aware that R really does symbolic manipulation in the way which you want, but I would have thought that this process would make a very pretty little problem to solve for you yourself, in that you could write a programme to analyse the original expression as a string of characters, whose
