...e some Pareto random variates using the inverse method. This is really straightfoward and my R function looks as below : pareto <- function(c, a, cnt=1000) { u <- runif(cnt) x <- (c / ((u ^ (1 / a)))) mean.theo <- ((c * a) / (a - 1)) mean.gen <- mean(x) cat('Pareto mean : theoritical', mean.theo, 'generated', mean.gen, '\n') return(x) } I am also giving the outputs below to illustrate my point. I understand the point that as 'a' is less than 2.0, the variance does not exist. But as 'a' approaches 1.0, the mean goes down approximate...

...ls package. To have a sense of the error I tried to look the mismatch between a unidimensional version of my distribution and estimate density at point zero with function density, dmvnorm and dnorm. At my big surprise dmvnorm and dnorm give very different result and dmvnorm match even better the theoritical distribution than the function density. How come? #sampling from triangular distribution X<-runif(10000)- runif(10000) X<-matrix(X,length(X),1) #dnorm estimate plot(-100:100/100, dnorm((-100:100)/100,mean(X),var(X)),col=2,type="l") #kernel density estimate lines(density(X)) #...

...have a theoretical question here. A 128K stream is a 128 KiloBITS (NOT kiloBYTES) per second stream; am I right? Is a 512k internet connection a 512 kiloBITS or 512 kiloBYTES connection? 128 KiloBITS = 16 KiloBYTES (8 bits = 1 byte). I am wondering if a 512k connection (upload and download) could THEORITICALLY handle 4 (512/128) or 32 (512/16) 128k streams? I am confused because I often read that to calculate the potential number of listeners with a given connection; you just divide the connection speed by the stream bit rate... is it true? In this case, how is doing SomaFM to handle 4000 listener...

...d known to very few implementors, perhaps only Xavier Leroy & Damien Doligez). So is there any code to fit the Ocaml GC requirements into LLVM abilities, ie to use LLVM to generate (eg JIT) code which respect Ocaml GC requirements. Of course, I do know that there are some typing issues and theoritical points which I deliberately ignore here. I'm supposing the guy wanting to LLVM for Ocaml is knowing that he seeks trouble. And Metaocaml is (unfortunately) nearly dead: future (in ocaml 3.11 or 3.12) dynamic libraries ability is not a full replacement! Even if one might generate Ocaml...

I was wondering what could be pros and cons of ztdummy vs proper timer device (i.e. X100P). I am going to set up an asterisk server in europe (to do trunking, to save bandwith) and I was wondering if it'll be OK to get it going with ztdummy. Furthermore, I have only a 1024/256kbps PPPOE DSL link and I need to squeeze 12 channels through, I was wondering which codec would be suitable

...'t think of looping over a vector in the same sense of an array. Also for me, a pointer to an 2nd vector element feels very similar to getting a pointer to a 2nd word of an 64 bit integer and less than a pointer to the 2nd element in an array. If we go toward treating the array model, theoritically one could use extract or insert for an array or we get rid of those operations, and have clients uses GEP to modify a vector element. Either of them seems wrong to me for vectors. -- Mon Ping On Oct 14, 2008, at 12:08 PM, Chris Lattner wrote: > > On Oct 14, 2008, at 11:02 AM, D...

It might be exciting to have an Ocaml with "exec" (surely it would allow new classes of programs), but static compilation seems clearly superior for existing programs, so my focus is there for now. > Of course, I do know that there are some typing issues and > theoritical points which I deliberately ignore here.

...I am facing a problem in extrapolation of data series. It is a series of Bond yields, I am having the yield for 1 year to 30 years. I want to find the yield for 0.5 year and 30.5 years. I used the Langrange's Extrapolation but the extrapolation deviates from the normal trend ( as we can see in theoritical yield curves) very sharply, as go on increasing my years from 30 years to 35 years as well as from 1 year to 10 days(i.e. 10/365 years), on both the ends. I am having nearly 20,000 interpolated points between 1 year and 30 yrs. Can anybody help me in my extrapolating problem. I know this questi...

Hi, I tried to simulate an ARIMA model by using arima.sim(), say arima.sim(n=100,list(order=c(1,0,1),ar=0.6,ma=0.9,sd=1), but the acf and pacf of simulated data using acf() and pacf() are so much different from the theoritcal acf and pacf. For instance, in my case, ar=0.6 and ma=0.9, so the acf for all lags should be greater than 0 based on the theoritical calculation, but the acf of simulated data always has some negative values which bothers me. Can any one tell me why? and how can I get the simulated data close to...

...mix isotropic definitions with anisotropic ones I don't know why. - The problem comes from adding the anisotropy parameter (a=anisoMatrix, in the function Kriging). When putting the anisotropy coefficient to one (ie isotropy), it doesn't work as well. - I have tested the script for several theoritical model of structure (sph,...), but it doesn't work as well - Even if the dimension of the data set is a vector in the case of irregular network (instead of a matrix in the case of a regular network), the anisotropy matrix has to stay with the dimension 2x2 (for a spatial network), and not a...
