Dear R-users, I am new to R and would like to use it for fitting the zipf distribution to some numeric data that I have. Here's the snippet that I use: library(VGAM) X <- read.table(file("~\\mydata.txt", encoding="latin1")) w <- as.vector(t((X[2]))) w <- w/sum(w) y <- (1:length(w)) fit = vglm (y ~ 1, zipf, tra=TRUE, weight=w)...

Using R, I plotted a log-log plot of the frequencies in the Brown Corpus using plot(sort(file.tfl$f, decreasing=TRUE), xlab="rank", ylab="frequency", log="x,y") However, I would also like to add lines showing the curves for a Zipfian distribution and for Zipf-Mandelbrot. I have seen these in many articles that used R in creating graphs. Thank you! [[alternative HTML version deleted]]

Hi, Is there a Zipf-like distribution RNG in R? Thanks, Weiguang

Dear R user, I want to estimate the parameter of ZETA or/and ZIPF distributions using R, given a series of integer values. Do you know a package (similar to MASS) or a function (similar to fitdistr) I can use to estimate the parameter of these distributions using MLE method? Otherwise do you know a function (which use MLE method to estimate distribution para...

Hi We have a couple of FSC Computers here which seem to have a very strange bios. I am trying to boot a MS-DOS disk to flash an Scsi Raid controller. Since the computer doesn't have a floppy anymore I tried syslinux from an usb stick. The menu loads fine but I cannot boot disc images with memdisk on this computer. It works fine on others, of course. But now comes the weird part, if I use the

Hi, I have a question on generating random variables based on zipf-mandelbrot distribution. So when I execute the following lines: ZM = lnre ("zm", alpha = 2/3, B=0.1) zmsample = rlnre (ZM, n =100) zmsample It generates 100 random values based on a zipf-mandelbrot distribution as below. But how do I make sure the generated random number is within the...

...80 times with a frequency of 1, another property occurs 9442 times with the same frequency. At the other end of the extreem, a certain property occurs once with a frequency of 5734, and another property occurs twice with a frequency of 1625. This kind of distribution is variously known as a "zipf", a "power law", a "Pareto", "scale free", "heavy tailed" or a "80:20" distribution, or coloquially "the dominance of the few over the many". The term I choose is a "log linear" distribution, because that makes no assumption...

Hi everyone. Newbie to statistics. I have 40 matrices of ~400 values. how may I determine whether the distribution follows zips law? response <-sample (1:20,400*4, replace= TRUE) Thank you vry much. -- View this message in context: http://r.789695.n4.nabble.com/A-introductory-question-about-Zips-law-Newbie-to-statistics-tp4521190p4521190.html Sent from the R help mailing list archive at

Dear all, How can I fit a truncated power law to a vector? I can't find a function to do that. If the function provides an AIC, even better. John

...number), so we could have used any signed or unsigned integer type for it instead of ubyte. UByte means we are limited to at most 256 structure fields but it also makes the bytecode representation more compact. (To remove this restriction, we may migrate to UInt in the future and use some kind of Zipf encoding to avoid increasing bytecode size in the common case.) There is a routine TargetData::GetIndexedOffset to convert any ptr + index list to the actual byte offset for a particular target machine.

I have a question about GetElementPtr. Suppose I have an GetElementPtr Instruction GI: %reg = getelementptr %ST* %s, uint 1, ubyte 2, ubyte 1, uint 5, uint 13 I want to check if this is the reference of a component of a structure, how can I do that? Should I check which operand of this instruction is 'ubyte' type? How can I do that in code? should I use ubyte *a =
