Hello, and please advise regarding any errors/omissions on my part.
However, the documentation for R's tcplot function in the evd package

Digital IO card and /proc/devices
Hi all,
I am having problems to get the SeaLevel IO card to work with CentOS distro.
Basically the card is being recognised and shown by lspci BUT /proc/devices
file is not updated with the new devices does anyone know why. ?
Could someone tell me what/where infos are needed to get /proc/devices to be
updated.
The reason I require the /proc/devices infos is because I want to run a mknod

lmomco in gev estimation
Hi guys,
I'm trying to use lmomco package. first I did the manual calculation on
what is the estimates scale and location parameter given L-CV=0.2, L1=1000
L-moments and k (shape parameter) =- 0.1. so what i get is:
location: 821.0445
scale: 260.7590
shape: -0.1000
#I assign this as GEV vectors using vec2par
GEVpara2<-vec2par(c( 821.0445 , 260.7590 ,-0.1),'gev')

GEV distribution fitted by L-moment graph
Hi,
I have been having difficulties in finding packages/ codes that simplify
plotting of a GEV fitted to dataset (by L-moments) that would print out
graph comprising dataset versus gumbel reduced variate n return period at
the same. Anyone can help me on this? Thanks.

odd issue with the with SIP over VPN
I've run into a odd issue where inbound calls to the SIP client work
fine, but outbound from the SIP client do not.
The path between the client and the server is as below.
N900 SIP client <-- OpenVPN --> Asterisk
The version of Asterisk in question is 1.6.0.18.
Any suggestions?

Fw: GPD/GEV export results for plot
Hi all,
I'd like to export the results of GPD or GEV analysis generated with the Extremes Toolbox for plotting in Grapher or Excel (for manipulation by our publications group). Is it possible to access the data used to generate the plots in extRemes, or do I need to code the analysis from scratch and write to file?
Thanks, Ben

QUADRATIC LINK FUNCTIONS FOR MLE ESTIMATE OF NON-STATIONARY GEV FITS
Hi All,
I am a newcomer to S/R. Could you please let me know how to model quadratic
trends for the mul/sigl link functions when fitting non-stationary GEV
distributions using the ismev package?
Thanks

QUADRATIC TREND FOR LINK FUNCTIONS ON NON-STATIONARY GEV
Hi All,
I am a newcomer to R. Could anyone explain me how to define link functions
for either mu/sigma to allow for quadratic trends in the same, when fitting
non-stationary GEV distributions?
Thanks

Saving fExtremes estimates and k-block return level with confidence intervals.
I am estimating a large model by groups. How do you save the results and?returns
the associated quantiles?
For this example I need a data frame

Ajustes GEV
Buenas a todos.
Estoy realizando unos ajustes a una serie de valores mensuales maximos
con ismev.
Los resultados son muy buenos. Por definicion, los valores que obtengo
del ajuste de la funcion de distribucion GEV, me dan valores de
periodos de retorno medios para los niveles de retorno que estudio.
El problema es que estos valores son los medios esperables para esos
periodos de retorno y yo, lo

bucle para que repita elementos
Hola a todos.
Estoy intentando implimentar un bucle que repita tantas veces un

Crash in R using embedded.
Hi,
I'm new to R, and am trying to embed R into another application.
I'm calling gev.fit() from the ismev package, and it is crashing somewhere
inside it.
gdb is not catching it, and valgrind is not showing any memory corruption
issues.
I suspect it's memory corruption, because it doesn't crash in exactly the
same spot each time.
I'm running R 2.12.2 on a 64 bit linux (Ubuntu

lmomco package and confidence limits?
Hello,
I am using the lmomco package (lmom.ub and pargev) to compute the GEV
parameters (location, scale, and shape), which are used to estimate
return values. I was wondering how/if I can calculate upper and lower
confidence (CI_u, CI_l) intervals for each return frequency using the
GEV parameters to fill-in the table below?
Xi (location) = 35.396
Alpha (scale) = 1.726
Kappa (shape) =

help needed! RMSE
i need HELPPP!! how do i calculate the RMSE value for two GEV models?first GEV is where the three parameters are constant.2nd GEV model a 4 parameter model with the location parameter is allowed to vary linearly with respect to time while holding the other parameters at constant.
is there any programming code for this?
i really really need help. please reply to me as soon as possible. thanks in

Respected Sir
I am a very new user of R. I want to ask a question about "the nortest
package". In this package how we can write the code of ad.test, cvm.test,
