similar to: linear models and colinear variables...

Is there a colinearty function implemented in R? I have tried help.search("colinearity") and help.search("collinearity") and have searched for "colinearity" and "collinearity" on http://www.rpad.org/Rpad/Rpad-refcard.pdf but with no success. Many thanks in advance, Peter Lauren.

Buenas tardes. Tengo una base de datos con 3200 variables. El nombre de todas ellas tiene un punto. Por ej., Canis.aureus. ¿Es posible cambiar ese punto por un espacio, en todas ellas, de forma automática? Esa quedaría así: Canis aureus Gracias [[alternative HTML version deleted]]

I'm sorry to all those who are tired of seeing my email appear in need of help. But, I've never coded in any program before, so this has been a difficult process for me. Is there a simple function to test for colinearity in R? I'm running a logistic regression and a linear regression. Thanks for the help! [[alternative HTML version deleted]]

I have just struggled to implement a Samba Domain Server, and have some remaining issues. I have a Samba PDC using tdbsam, managing a domain called RHEA. I have (finally) configured a new Samba Domain Server (AUREUS) using winbind and idmap_rid. When I am logged in to RHEA as user GMCH I can access a TMP share on AUREUS (at last). Running 'getent passwd' I get (inter alia):

Hi all, I read in a text book, that you can examine a variable that is colinear with others, and giving different ANOVA output and explanatory power when ordered differently in the model forula, by modelling that explanatory variable, against the others colinear with it. Then, using that information to split the vector (explanatory variable) in question, into two new vectors, one should

Dear all: I try to analyse a dataset which contain one binary response variable and serveral predict variables, but multiple colinear problem exists in my dataset, some paper suggest that logistic regression for principle components is suit for these noise data, but i only find R can done principle component regression using "pls" package, is there any package that can do the task i

Hi, I am trying to compile R with ICU support. I am following https://cran.r-project.org/doc/manuals/R-admin.html#Building-from-source I have downloaded and extracted https://www.stats.ox.ac.uk/pub/Rtools/goodies/ICU_531.zip to W:\R-3.5._\App\R-Portable\ICU I have modified MkRules.local # set to use ICU USE_ICU = YES # path to parent of ICU headers ICU_PATH = w:/R-3.5._/App/R-Portable/ICU I

hello, I asked about this simulation a few days ago, but still i can't get what i need. I have 2 units: icu and regular. from icu I want to take 200 observations from binomial distribution, when probability for disease is: p=0.6. from regular I want to take 300 observation with the same probability: p=0.6 . the distribution to detect disease when disease occurred- *for someone from icu* - is:

Hi group: I have a data set, which has severe colinearity problem. While running linear regression in R and SPSS, I got different models. I am wondering if somebody knows how to make the two software output the same results. (I guess the way R and SPSS handling singularity is different, which leads to different models.) Thanks.

Hi R experts, I'm attempting to run Linear Discriminant Analysis using the lda function in the MASS package. I've got around 50 predictor variables and one response variable. My response variable has 5 numeric categories that represent different clusters of fish abundance data (clusters were developed using Bray-Curtis and NMDS), and my predictor variables are environmental variables that

The current implementation is O(n) and I took care to keep it at that. For the proposed term

Hello, I've looked for a BIDI HOW-TO, but did not find any. I use wine-0.9.5, and run IE using ies4linux. It works great including Hebrew showing Hebrew text correctly. The problem is that I could not write any Hebrew character... Whenever I type a character I get "?". So I've looked at wine-bidi issues, and found that I need to compile wine with icu library. I did! using

I've just been looking at ICU with an eye to reworking the unicode queryparser patch to use it. A few things have jumped out so far which make we wonder if it's the best option. I don't really know what the alternatives are though (currently QueryParser uses glib's unicode routines). The first is that there seems to be bad version skew. Ubuntu breezy (the latest release) has

Hello, For basic linear regression lm() does the job well, for datasets that are larger than memory biglm() seems to work. I'm working on a parallel implementation of multiple linear regression for datasets that are too large for memory. Currently I am working over least squares: calculating: t(X) %*% X and t(X) %*% y separately in parallel on each node This generates a

Dear all users, I"d like to ask you how to make decision about colinearity among categorical independent variables when the model is multinomial logistic regression. Any help is appreciated, Niklas [[alternative HTML version deleted]]

Is it an undocumented (at least I missed it if it's documented) feature of the reshape function to do numeric variables followed by character? I ask because that seems to be the case below. > str(rcw) 'data.frame': 23 obs. of 21 variables: $ ICU : int 1 18 17 9 22 19 6 16 25 26 ... $ Q6.RC.1 : chr "SM" "JF" "IW"
