similar to: Error in spdep: system is computationally singular

Greetings to the list, I was trying to estimate spatial error model in R, somehow I got the message below. Would you please help me with it? Many thanks in advance. Error in solve.default(asyvar, tol = tol.solve) : system is computationally singular: reciprocal condition number = 5.6964e-18 Regards, Dong

We are happy to announce the first CRAN release of rTRNG version 4.20-1. rTRNG is a package for advanced parallel Random Number Generation in R. It relies on TRNG (Tina?s Random Number Generator, <https://numbercrunch.de/trng/>), a state-of-the-art C++ pseudo-random number generator library for sequential and parallel Monte Carlo simulations. In particular, parallel random number generators

Dear list, (also sent to Roger Bivand, but perhaps somebody of you can help me also) I am trying to use package spdep for fitting an SAR model with errorsarlm. However, I am not sure how to make a valid nb object out of my neighborhood. As far as I have seen, there is no documentation for nb.object. I have done the following: class(pschmid$nb) <- "nb" # pschmid is a prab object as

Hello, Has anyone modified the errorsarlm in the R package spdep to allow for more than a single spatial autocorrelation coefficient (i.e. 'lambda')? Or, if not, any initial suggestions on how to make that modification? I have looked at the source code for the function and realize that any attempt to do it on my own would require much dedication, so would like to

Hello, I am trying to extract an estimator for the bread of the sandwich function. I used bread(fitted model) however it seems that I have missed something as an error message "no applicable method for "bread" appears. My fitted model is a Spatial simultaneous autoregressive error model.(errorsarlm in spdep package) Can anyone please tell me what I might be doing wrong? Your

Hi all, I've been curious about using hardware true random number generators in my VM clusters. This got me wondering about the VM's /dev/random source... If I setup a hardware TRNG on the host, would the VM's also benefit from it?

Dear R developers: I am a PHD candidate student in the school of public health of Peking University and my major is genetic epidemiology.

When I run a macro that uses RExcel, I get a dialog box that says "Microsoft Excel is waiting for another application to complete an OLE action." There is no error in the RExcel commands in the macro, of that I am sure. The box appears to be related to the inclusion of RunRFile commands. The macro will run through the second RunRFile command, but will not execute the

Dear List, I have some problem with my simulation code. Here is output from R: > sim.sp <- function(data,CM,n,N) + { + C <- matrix(rep(NA,N),ncol=1) + for(i in 1:N) + { + j <- n + xx <- which(colSums(CM[j,])==1) + V <- names(xx) + V <- paste(V, collapse="+") + V <- paste("SBA~", V) + rd <- round(nrow(data)*(2/3)) + d <-

Hi All, I had some questions regarding the SystemZ implementation and missing instructions. I've been comparing the IBM z/Architecture Reference Summary (SA22-7871-08) to the output of "llvm-tblgen SystemZ.td -print-enums -class=Instruction" and noticed that there's 525 missing instructions. For example, if I look at instruction "M" (page 16) with opcode 0x5c (M

Hello, I have been using the package "spdep" to run spatial regressions on a data set with about 2500 observations.

I'm trying to use the spdep package to calculate this: y = rho W y + e I don't want to use explanatory variables, just the lag from the dependent variable. How would I code this?

I halved the volume of the sample before encoding with `sox -v 0.5 floex.wav quiet.wav` and now I can't ABX it succesfully anymore. So the artifact I heard was just clipping when encoding or decoding. Opus remains unbeaten for me at 133 kbps. That's totally awesome.
