Hello- Since my data bank in SPSS has > 40 variables, I think that R crashes because of the memory limit. In Maindonald?s UsingR text, on pg 3, there?s a footnote that reads: "If you want larger memory space than the default you may want a target akin to <path to binary>\rw091\bin\rgui.exe --visize 30M --nsize 1000K [The default is --vsize 6M --nsize 250K

Hello- While I was reading a tutorial book for R (actually, for S-Plus:Brian S. Everitt. A Handbook of Statistical Analysis using S-PLUS. Chapman & Hall, London, 1994) I tried to execute this simple exercise: > x <- -c(1,2,3,4,5,6) > X <- -c(10,11,12,100,-5,-6) >x+X [1] -11, -13, -15, -104, 0, 0 As you can see, the added vectors resulted in

Hello all, I would like to plot the emperical CDF, normal CDF and pareto CDF in the same graph and I amusing the following codes. "z" is a vector and I just need the part when z between 1.6 and 3. plot(ecdf(z), do.points=FALSE, verticals=TRUE, xlim=c(1.6,3),ylim=c(1-sum(z>1.6)/length(z), 1)) x <- seq(1.6, 3, 0.1) lines(x,pgpd(x, 1.544,0.4373,-0.2398), col="red") y

Hi, guys, I need to simulate Pareto distribution. But I found 'rpareto' didn't exist in R. And it seems that Pareto distribution don't have mathematical relationships with other distributions. What can I do? Thanks a lot. Ni --------------------------------- [[alternative HTML version deleted]]

Dear all, I am trying to simulate from truncated Pareto distribution. I know there is a package called PtProcess for Pareto distribution...but it is not for truncated one. Can anyone please help me with this? Thanks in advance. Cassie [[alternative HTML version deleted]]

In https://en.wikipedia.org/wiki/Pareto_distribution, it is clear what the parameters are for the pareto distribution: *xmin *the scale parameter and *a* the shape parameter. I am using rmutil to generate random deviates from a pareto distribution. It says in the documentation that the probabilty density of the pareto distribution The Pareto distribution has density f(y) = s (1 + y/(m

Hi, I would like to use the following codes to plot the CDF for pareto distribution. Before doing this, I have plot the emperical one. x <- seq(1.6, 3, 0.1) lines(x,pgpd(x, 1.544,0.4477557,), col="red") Could anyone give me some advice whether the above codes are correct? Many thanks. -- View this message in context:

Hello Well I am relatively new so some of these issues may not fall under the subject that I have used. 1. How do I do a Pareto. Following is the approach I took. My data looks like this df2_9 Reaason.for.failure Frequency 1 Phy Conn 1 2 Power failure 3 3 Server software 29 4 Server hardware 2 5 Server out of mem 32

Dear R helpers, I have a bimodal dataset dealing with loss amounts. I have divided this dataset into two with the bounds for the first dataset i.e. dataset-A being 5,000$ to 100,000$ and the dataset-B deals with the losses exceeding 100,000$ i.e. dataset-B is left truncated. I need to fit truncated normal disribution to dataset - I having lower bound of 5000 and upper bound of 100,000. While I

Hi all I have a large dataframe with (among others) a categorical variable of 52 levels and would like to create a barplot with the bars ordered in decreasing frequency of the levels. I belive it is referred to as a pareto plot. Consider a subset where I keep only the categorical variable in question. # Example: v1 = c("aa", "cc", "bb", "bb",

I would like to fit a Pareto Distribution and I am using the following codes. I thought the fitted (fit1) should be the fitted value for the data, is it correct? As the result of the "fitted" turns out to be a single value for all. fit=vglm(ycf1 ~ 1, pareto1(location=alpha), trace=TRUE, crit="c") fitted(fit) The result is fitted(fit) [,1] [1,] 0.07752694

I would like to fit a Pareto Distribution and I am using the following codes fit=vglm(ycf1 ~ 1, pareto1(location=alpha), trace=TRUE, crit="c") fitted(fit) But the fitted values turn out to be the same for each observation. I guess the problem is with "ycf1 ~ 1", I would be grateful if anyone can give me some advice on how to define the formula. Many thanks -- View this

Dear R users, Could you please help me out. I am in trouble as I am unable to model graphs to explain the GARCH (1 , 1) model, the Hill estimator (of alpha), and the Pareto estimator. I just got introduce to R. I am working on a paper which must be worked from R. You look at the difficulty I had from the text below. [1] "DAX" "DAX_CAC" "DAX_CAC40"

Dear R helpers, I need to use KS and AD test for Generalized Pareto and Generalized extreme value. E.g. if I need to use KS for Weibull, I have teh syntax ks.test(x.wei,"pweibull", shape=2,scale=1) Similarly, for AD I use ad.test(x, distr.fun, ...) My problem is fir given data, I have estimated the parameters of GPD and GEV using lmom. But I am not able to find out the distribution

1) The Pareto P(alfa) distribution is defined by its density f(x|alfa) =alfa*X^(-alfa-1) over (1 to infinity). Show that it can be generated as the -1/alfa power of a uniforme variate. Plot the histogram and the density. 2) The Poisson distribution P(lambda) is connected to the exponential distribution through the Poisson process in that it can be simulated by generating exponential random

Hello- This goes for all those insterested in contributing with the effort to have better Debian documentation, and are willing to submit material to the Science section of the DURG, in order to divulge R to a wider public.

Hello- I had to reinstall my system completely, due to a cracker (a script kiddie). I've added the CRAN recommended lines to my sources.list. I removed my old R package (0.92, I believe) and intalled a new one, but it's the 1.3.1 If I remember correctly, this is not the __latest__ version is it? What's happening than, since my /etc/apt/sources.list is correct? TIA Regards

Hello- This is off-tpoic, but of interest. There's a remote exploit bug on rsync, that was posted on Linux Today. I post this here because apparently it hasn't been mentioned (yet) on the Debian security advisory. The package list is not updated either. Perhaps this is what happened to CRAN when it was cracked... Maybe you admins at CRAN would want to contact the debian-security

Hi- I've upgraded to Debian Woody. I've downloaded and installed the new R-1.4.1. However, it crashes on me, complaining about libblas.so.2.
