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 me are the errors. ###CROSS-VALIDATION ###################### # install.packages( "robustbase" ) # install.packages( "MASS" ) # install.packages( "quantreg" ) # install.packages( "RobPer" ) # install.packages("devtools") # library("devtools") # install_github("kloke/hbrfit") #install.packages('http://www.stat.wmich.edu/mckean/Stat666/Pkgs/npsmReg2_0.1.1.tar.gz') # install.packages( "cvTools" ) library(robustbase) library(MASS) library(quantreg) library(RobPer) library(hbrfit) library(cvTools) X <- c(5,3,2,4,7,6,9,3,7,11,1,6,4,5,6,9,4,5,34,2,1,3,12,8,9,7,4,12,19,21) Y <- c(25,24,23,19,17,14,13,14,25,13,17,25,14,13,19,25,16,16,20,21,25,19,12,11,9,28,21,10,2,8) Z <- c(34,32,12,23,54,12,13,54,52,32,39,19,32,12,11,10,9,8,45,34,23,26,29,6,35,47,21,29,26,25) reg1 <- lm( Y ~ X+Z ) reg <- lmrob( Y ~ X + Z) Huber <- rlm( Y ~ X +Z) Tukey <- rlm( Y ~ X+Z, psi = psi.bisquare ) L1 <- rq( Y ~ X + Z, tau = 0.5 ) fast <- FastTau(model.matrix(~X+Z),Y) HBR<-hbrfit(Y ~ X +Z) cvFit(lmrob,formula=Y ~ X + Z, cost=rtmspe, K=5, R=100) cvFit(lm,formula=Y ~ X + Z, cost=rtmspe, K=5, R=100) cvFit(rlm,formula=Y ~ X + Z, cost=rtmspe, K=5, R=100) cvFit(rlm,formula=Y ~ X + Z, psi = psi.bisquare, cost=rtmspe, K=5, R=100) cvFit(rq,formula=Y ~ X + Z, tau=0.5, cost=rtmspe, K=5, R=100) cvFit(FastTau(model.matrix(~X+Z),Y),cost=rtmspe,K=5,R=100) cvFit(hbrfit,formula=Y ~ X + Z, cost=rtmspe, K=5, R=100) ###################### ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
