Dear R-experts, Doing cross-validation for 2 robust regressions (HBR and fast Tau). I can't get the 2 errors rates (RMSE and MAPE). The problem is to predict the response on the testing data. I get 2 error messages. Here below the reproducible (fictional example) R code. #install.packages("MLmetrics") # install.packages( "robustbase" ) # install.packages(

Dear R-experts, I guess I have a problem with my fast function (fast tau estimator) here below. Indeed, zero errors look highly suspicious. I guess there is a bug in my R code. How could I correct my R code ? # install.packages( "robustbase" ) # install.packages( "MASS" ) # install.packages( "quantreg" ) # install.packages( "RobPer" ) #

Dear R-experts, I am trying to do cross-validation for different models using the cvTools package. I can't get the CV for the "FastTau" and "hbrfit". I guess I have to write my own functions at least for hbrfit. What is going wrong with FastTau ? Here below the reproducible example. It is a simple toy example (not my real dataset) with many warnings, what is important to

The script below successfully produces a biplot of the data but the 'site names' (rows) and the names of the 'response variables' (columns) are shown as simple numerals (rather than the column and row names). How might I 'enforce' the use of the row/column names used in the datafile (section of datafile shown below)? Can anyone help, please? Section of datafile sample a b

Dear R-experts, I am trying to bootstrap (and average) the median squared error evaluation metric for a robust regression. I can't get it. What is going wrong ? Here is the reproducible example. ############################# install.packages( "quantreg" ) library(quantreg) crp <-c(12,14,13,24,25,34,45,56,25,34,47,44,35,24,53,44,55,46,36,67) bmi

R-experts, I have fitted many different lines. The fast-tau estimator (yellow line) seems strange to me?because this yellow line is not at all in agreement with the other lines (reverse slope, I mean the yellow line has a positive slope and the other ones have negative slope). Is there something wrong in my R code ? Is it because the Y variable is 1 vector and should be a matrix ? Here is the

Hello, If you want to bootstrap a statistic, I suggest you use base package boot. You would need the data in a data.frame, see how you could do it. library(boot) bootMedianSE <- function(data, indices){ d <- data[indices, ] fit <- rq(crp ~ bmi + glucose, tau = 0.5, data = d) ypred <- predict(fit) y <- d$crp median(y - ypred)^2 } dat <-

You need to pay attention to the documentation more closely. If you don't know what something means, that is usually a signal that you need to study more... in this case about the difference between an input variable and a design (model) matrix. This is a concept from the standard linear algebra formulation for regression equations. (Note that I have never used RobPer, nor do I regularly

Dear R-experts, Here below my reproducible R code. I want to add many straight lines to a plot using "abline" The last fit (fast Tau-estimator, color yellow) will not appear on the plot. What is going wrong ? Many thanks for your reply. ########## Y=c(2,4,5,4,3,4,2,3,56,5,4,3,4,5,6,5,4,5,34,21,12,13,12,8,9,7,43,12,19,21)

Hi Samba community, Last year we upgraded from version 3.0.10 to 3.0.20b and at the same time switch from NT-domain controller membership to AD membership. After this upgrade we began to experience that drives sometimes were not mapped. We saw this both on our Citrix servers and on our XP PCs. A couple of weeks back we then moved to 3.0.21b in the hope that this misbehaviour would

We're looking at getting an HBR (that's a technical term, honkin' big RAID). What I'm considering is, rather than chopping it up into 14TB or 16TB filesystems, of using xfs for really big filesystems. The question that's come up is: what's the state of xfs on CentOS6? I've seen a number of older threads seeing problems with it - has that mostly been resolved? How does

I forgot, you should also set.seed() before calling boot() to make the results reproducible.

Hi, I've been looking through the news archives but haven't found this.. Perhaps I just didn't see the forest for the trees... :) My question is about the format of text files. Files created on Linux show up on Windows (via samba) without the newline. Is there a parameter setting that I'm missing? How do I get compatibility between the two? Thanks, Mike -- "My Humility

Hi everyone, I'm running Samba 1.9.18p10 and it works great. But I can't get it to announce to other subnets that are on the other side of a router. I've added "remote announce = 192.168.1.255" to smb.conf (my machine is in 192.168.0.0 subnet) and there are no other NT machines in any of the subnets. What should I look for? Thanks, Joe
