Dear all, how can I use vcovHC() to get robust/corrected standard errors from an arima() output? I ran an arima model with AR(1) and got the estimate, se, zvalue and p-value using coeftest(arima.output). However, I cannot use vcovHC(arima.output) to get corrected standard errors. It seems vcovHC works only with lm and plm objects? Is there another way I can get robust/corrected

Hi, I am currently working on fitting a mixture density to financial data. I have the following data: http://s000.tinyupload.com/?file_id=00083355432555420222 I want to fit a mixture density of two normal distributions. I have the formula: f(l)=πϕ(l;μ1,σ21)+(1−π)ϕ(l;μ2,σ22) my R code is: normalmix<-normalmixEM(dat,k=2,fast=TRUE) pi<-normalmix$lambda[1] mu1<-normalmix$mu[1]

Dear list, I have found an unusual behavior and would like to check if it is a possible bug, and if updating R would fix it. I am not sure if should post it in this mail list but I don't where is R bug tracker. The only mention I found that might relate to this is "If times is a computed quantity it is prudent to add a small fuzz." in rep() help, but not sure if it is related to

Hello, eveRybody, I've been trying to find the origin for the following formatting-"inconsistency": E. g., look at the number of digits in summary.defaults()'s output when NAs occur: in my example below the number of NA's is displayed as an integer, the rest as numeric (floating point numbers): > summary.default( c( 1:2, NA)) Min. 1st Qu. Median Mean 3rd Qu.

Dear R-helpers: I am trying to fit a multivariate Cox proportional hazards model, modelling survival outcome as a function of treatment and receptor status. The data look like below: # structure of the data str(sample.data) List of 4 $ survobj : Surv [1:129, 1:2] 0.8925+ 1.8836+ 2.1191+ 5.3744+ 1.6099+ 5.2567 0.2081+ 0.2108+ 0.2683+ 0.4873+ ... ..- attr(*, "dimnames")=List of 2

Hi I'm getting an error message with the roots() function in the vars package. Even the example in the help file comes up with an error: > data(Canada) > var.2c <- VAR(Canada, p = 2, type = "const") > roots(var.2c) Error in UseMethod("roots") : no applicable method for 'roots' applied to an object of class "varest" The error is odd, for

Pues parece que el problema si es de lme4, cuya versión 1.0-4 se publicó en septiembre de este año. En la página en cran del paquete pone "The core computational algorithms are implemented using the Eigen C++ library for numerical linear algebra and RcppEigen "glue" " . El tema es que al utilizar esta versión junto con la librería boot, el tiempo de cálculo se incrementa

Hola buenas. al final corri el siguiente código en mi máquina de casa. El problema es que ha habido algún cambio en la librería lme4, que hace incompatible los nuevos objetos lmer con la funcioón pamer.fnc. En este tipo de situaciones imagino que lo propio sería ponerme en contacto con el autor o intentar corregir yo mismo el código o incluso ambas. ¿Es decortes escribir al autor reportandole el

Estimado Javier Villacampa Gonzáles Si una persona se toma el trabajo de desarrollar y compartir, como es el caso de R, seguramente conoce de problemas que tuvo que decidir mientras escibía el código, y estará agradecido porque hay gente que utiliza su aporte, su trabajo no fué a la nada, todo lo contrario. En mi caso un solo autor tuvo una respuesta negativa para con migo. Javier Marcuzzi

Hi, I get an error from loadNamespace in the following situation (on R-2.15.3, R-devel 2013-03-26 r62409, and fresh R-3.0.0): - package A has an optional (suggests) dependency to package C, which is tested at load time in .onLoad, via require(). - package B depends on package A, which is loaded when B is lazy-loaded at install time. - package B is installed with package C installed If one now

My advice would be to avoid the network in one of the following ways 1. Store installed packages on your local drive 2. Copy the installed packages to a tempdir on your local drive each time the script is executed 3. Keep an R session running in perpetuity and source the scripts within that everlasting session 4. Rewrite your scripts to use base R only. I suspect this solution list is

You had Rserve by Simon for close to 20 years. There isn't

It's possible to run R (or a c parent process) as a background process via a named pipe, and then write script files to the named pipe. However, the details depend on what shell you use. The last time I tried (which was a long time ago), I created a small c program to run R, read from the named pipe from within c, then wrote it's contents to R's standard in. It might be possible to

Hello R Community, I inadvertently updated packages via R Studio when a package was open. Now when R Studio is opened the message below appears in the console panel. Error in loadNamespace(name) : there is no package called ?yaml? Error in loadNamespace(name) : there is no package called ?yaml? When running R code, so far the only function that has not worked is datatable () in the ?DT?
