search for: statitics

I would like to buy a basic statistics book (experimental design, sampling, ANOVA, regression, etc.) with examples in R. Or download it in PDF or html format. I went to the CRAN contributed documentation, but there were only R textbooks, that is, textbooks where R is the focus, not the statistics. And I would like to find the opposite. Other text I am trying to find is multivariate data

Hi ! mu name is Paolo and I teach statistic in a small college in Brazil and we use Linux. We started to use R as our statitical software. I,ve been trying to use some commands I see in the documentation online but i doesn not work. Commands like simple.hist.and.boxplot and others related with graphing. Do I need a special ppackage ? how do I load it ? Thanks

Hi, I am running the following example which can be found on page 12 of the pdf file of COIN package wt<-wilcox_test(pd~age,data=water_transfer,distribution="exact", conf.int=TRUE) "wt" actually contains the estimate of difference in location and the confidence interval of it. I am just wondering how can I extract these values? From the examples, I understand that the

Dear All, I am economist and working on poverty / income inequality. I need descriptive statitics like the ratio of education expentitures between different income quintiles where each household has a different weight. After a bit of google search I found 'Hmisc' and 'quantreg' libraries for weighted quantiles. The problem is that these packages give me only weighted quintiles;...

Hi All I have to run multiple stimations and to compute Likelihhod ratio. If I compute ls function with coef and summary I can extract "outputs" that I need. I am not able to find something similar to log liklihood.... Can you pease tell me running a ls function x on y how to extract if posible LR statitic or Likelihood or Log likelihood. Many thanks in advance. If you send me

hello all, for my diploma-thesis i want to statitically analyze near-infrared-spectra. a spectrum is given by the y-values of 1038 equi-distant x-points. in nature, a spectrum is a continuous curve. for analysis, every x-point is seen as a statistical variable. now my problem: first, i read a csv-table in a data.frame called sTable via read.table. besides some meta-data there are 1038 variables

...so much as a flicker of disk activity. (strace is similarly quiet) Initially, I gave up on waiting the first couple of attempts, and upgraded from e2fsprogs-1.27 to 1.28-WIP-0817. That didn't seem to make any difference. I'm invoking e2fsck with '-d -v -tt', and stage1 spat out statitics when it finished, but stage2 is just sitting there.. Any ideas? It sounds like a e2fsck bug, but until I know the filesystem is clean, I don't want to clear the dirty flag and mount it read/write. The "backup/mkfs/restore" isn't quite practical in this case as I don't have...

...state in each trial (say, the controlled point on the screen ended to the right or to the left) on the exerted force. I think that this later factor should also be considered as a random effect, but I am not sure. My question is how do I specify this model using aov() in R. I am not very used to statitics, and perhaps my question has a trivial answer. If this is the case, please give the pointers where I can find more information on this problem. Thank you in advance for any help, -- Rafael Laboissiere

Does anyone have any log analysis tools? I'm currently configured with "log file = /usr/local/samba/var/log.%m", which makes identifying issues with any one client easy, but doesn't provide me with an overall picture of what has been happening. What I'd like to be able to produce is a report showing, for a given unit time, the total number of clients that have connected,

Dear UseRs, Suppose I have data regarding smoking habits of a prospective cohort and wish to determine the risk ratio of colorectal cancer in the smokers compared to the non-smokers. What do I do at the end of the study with people who die of heart disease? Can I just censor them exactly the same as people who become uncontactable or who die in a plane crash? If not, why not? I'm thinking

my teachers doesnt understand R and I don't know how to use SAS. Anyone interested in translating my codes to test whether your SAS codes are as good as R??? I can test it on SAS codes once you have translated it .... regards:working: -- View this message in context: http://old.nabble.com/Translation-from-R-codes-to-SAS.-tp26486117p26486117.html Sent from the R help mailing list

Hello. We''re currently using a Sun Blade1000 (2x750MHz, 1G ram, 2x160MB/s mpt scsi buses, skge GigE network) as a NFS backend with ZFS for distribution of free software like Debian (cdimage.debian.org, ftp.se.debian.org) and have run into some performance issues. We are running SX snv_48 and have run with a raidz2 with 7x300G for a while now, just added another 7x300G raidz2 today but

Hi This is a question regarding classification performance using different methods. So far I've tried NaiveBayes (klaR package), svm (e1071) package and randomForest (randomForest). What has puzzled me is that randomForest seems to perform far better (32% classification error) than svm and NaiveBayes, which have similar classification errors (45%, 48% respectively). A similar difference in

Guys (and girls), I\'ve been testing Ogg Vorbis quality at home, and I thought I\'d share the results with you. For those who want the conclusion, Vorbis 1.0 RC3 sounds better than LAME 3.70 vbr/cbr (which I\'m told now that it\'s broken for VBR), at less bitrate, however, it\'s not perfect (and probably never will, since it\'s a lossy audio codec) and could use some
