Dear all, I am running a code using bootstraps for estimating standard errors but the mac crashes. When I use small number of bootstraps (100) it works fine but if I increase that number it crashes.
Thanks in advance dimitris The code, the error and my mac characteristics are the following: ##############code##################### qr.1<- rq(y~factor(year)+factor(state)+x1+I(x^2)+I(x^3), tau=0.05, data=data1) s.qr1.05 <- summary(qr.1, se="boot", R=1000)$coefficient ##############error##################### *** caught segfault *** address 0x1de9e000, cause 'memory not mapped' Traceback: 1: .Fortran("xys", as.integer(m), as.integer(n), as.integer(p), as.integer(R), as.integer(m + 5), as.integer(p + 2), as.double(x), as.double(y), as.double(tau), as.double(tol), flag = integer(R), coef = double(p * R), resid = double(m), integer(m), double((m + 5) * (p + 2)), double(m), xx = double(m * p), yy = double(m), as.integer(s), PACKAGE = "quantreg") 2: boot.rq.xy(x, y, s, tau) 3: boot.rq(x, y, tau, ...) 4: summary.rq(qr.05.nox, se = "boot", R = 1000) 5: summary(qr.05.nox, se = "boot", R = 1000) Possible actions: 1: abort (with core dump, if enabled) 2: normal R exit 3: exit R without saving workspace 4: exit R saving workspace Selection: ###############characteristics##################### Mac OS X version 10.5.4 Model Name: MacBook Model Identifier: MacBook4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 3 MB Memory: 4 GB Bus Speed: 800 MHz Boot ROM Version: MB41.00C1.B00 -- View this message in context: http://www.nabble.com/Mac-crash--Probably-memory-problem-tp19860892p19860892.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list 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.
