Hello all, I would like to know how to call sas code in R. Since I simulate data in R and I need to use sas code (garch-t,egarch and gjr) to estimate it. I need to simulate 500 times with 2000 obs. How I can call that code in R.Also, how I can keep the parameters from the estimate. j=1:500 i=1:2000 sas code keep parameters. Best Appreciate, Luck

Hi R-users, I try to use "solve" to find the answer of this linear equation a=x*b where a is 2*1 matrix and b is 2*2 matrix.I would like to get x so I call y<-solve(a,b) but this one happen "a is 2*1 matrix" so what I should do . Thanks Luck

Hi, I created a function for obtaining the normal cumulative distribution (I know all this already exists in R, I just wanted to verify my understanding of it). below is the code I came up with. cdf<-function(x) { erf<-function(x) { # approximation to the error function (erf) of the # normal cumulative distribution function # from Winitzki

Dear R-helpers, I was wondering if anyone has or knows someone who might have an implementation of algorithm for estimating garcht-t, egarch and gjr models. I try to use Fseries but I don't know how to code these models. Thanks a million in advance, Sincerely, Nongluck

Hi all. I may be wrong, (and often am), but in trying to determine how to calculate the erf function, the documentation for 'pnorm' states: ## if you want the so-called 'error function' erf <- function(x) 2 * pnorm(x * sqrt(2)) - 1 ## and the so-called 'complementary error function' erfc <- function(x) 2 * pnorm(x * sqrt(2), lower=FALSE) Should, instead, it read:

Do any of the R libraries have an implementation of the Inverse Error Function (Inverse ERF)? ref: http://mathworld.wolfram.com/InverseErf.html http://functions.wolfram.com/GammaBetaErf/InverseErf/ Thanks, Nathan [[alternative HTML version deleted]]

how R implement qnorm() I wonder anyone knows the mathematical process that R calculated the quantile? The reason I asked is soly by curiosity. I know the probability of a normal distribution is calculated through integrate the Gaussian function, which can be implemented easily (see code), while the calculation of quantile (or Zα) in R is a bit confusing as it requires inverse error function (X

Hallo Liste, hat sich schon mal jemand mit 2 Faktor Auth f?r dovecot besch?ftigt? Es geht dabei nicht nur um die Absicherung einer Weboberfl?che sondern direkt die Absicherung der Standard pop/imap Verbindungen des Clients. Wir machen das auth bisher ?ber MySQL.? Rein technisch w?rde das gehen, da man die Password-Query beliebig anpassen und auch mit allow_nets arbeiten kann. Es w?re eher die

Hi, I have some general questions about statistical analysis for a research dataset and a request for advice on using R and associated packages for a valid analysis of this data. I can only pose the problem as how to run multiple ANOVA tests on time series data, with reasonable controls of the family-wise error rate. If we run analysis at many small sections of a long time-series, the Type-I

Dear all, The package NORMT3 which computes the erf, erfc functions as well as the exact values of the convolution of a Gaussian with a Student's t 3 distribution has been enhanced with the addition of a function to compute Faddeeva's function. Thanks to Krishna Myneni for this addition. Guy Nason [[alternative HTML version deleted]]

Hi Duncan I am facing a build error about __builtin_iceil when compiled with dragonegg using -ffast-math option. My dragonegg is built with gcc-4.7.0 (I am compiling namd spec benchmark here again). Any idea? g++ -march=bdver2 -save-temps -fplugin=/home/anboyapa/install/bin/dragonegg.so -O2 -march=bdver2 -save-temps -fplugin=/home/anboyapa/install/bin/dragonegg.so -mno-fma -mfma4 -ffast-math

I want to fit some p-values to a beta distribution. But the problem is some of the values have 0s and 1's. I am getting an error if I use the MASS function to do this. Is there anyway to get around this? -- Thanks, Jim. [[alternative HTML version deleted]]

I believe that this may be more appropriate here in r-devel than in r-help. The normal hazard function, or reciprocal Mill's Ratio, may be obtained in R as dnorm(z)/(1 - pnorm(z)) or, better, as dnorm(z)/pnorm(-z) for small values of z. The latter formula breaks dowm numerically for me (running R 2.4.1 under Windows XP 5.1 SP 2) for values of z near 37.4 or greater. Looking at the pnorm
