similar to: Seeking Code for Chaid or Similar

I have a large dataset (questionnaire results) of mostly categorical variables. I have tested for dependency between the variables using chi-square test. There are an incomprehensible number of dependencies. I used the chaid() function in the CHAID package to detect interactions and separate out (what I hope to be) the underlying structure of these dependencies for each variable. What typically

Hi..I am trying to run CHAID in R..I have installed the sofyware Party and trying to use the function ctree() to carry out the analysis. but I am getting the following message Error in terms.default(formula, data = data) : no terms component . I am having some Likert scale variable where I have variables like "Overall satisfaction"(Dependent Variable),"Product quality", Brand

Can I say that RPART is a modified algo of CART and PARTY a modified of CHAID?

Dear R-helpers, I just search if is there something for AID and CHAID in R: one message in this list (last year) without success and no possibility. News about? If "no" let's me know because some friends are looking for thesis and this could be a usefull job. bye -- Daniele Medri

Could you please let me know how to run chaid in R.     Thanks, Saumyha [[alternative HTML version deleted]]

Dear Colleagues, I've been looking for a function that can perform a tree analysis, similar to CHAID or QUEST. The key point is that in this case the variables are not binary but nominal (10 different values), so "tree" (from the tree package) won't work. Does anybody know help?

Quer?a saber si existe alguna funci?n de R para realizar el algoritmo CHAID de ?rbol de clasificaci?n, existen de J48 por ejemplo pero no encuentro nada de este algor?tmo.

Hi., I would like to conduct a CHAID tree analysis - Chi-square Automatic Interaction Detector. >From what I can make out from MASS, tree, rpart, and a quick search it isn't available as a package. Is that correct or have I missed it? Has anyone an available implementation of it? Thanks Stephen Nana Mail <http://mail.nana.co.il> - Get Your Free Personal Outlook 2003 Now

Michael thank you very much, what about the options I have tried all without success. Try again to send a message to the list by changing the subject line.

Hi All, I need to access the node informations (viz. child nodes, split variable, split criterion etc.) for different trees packages like, CHAID, rpart, party etc. Is there an in-built function which I can use to get the requied info?

Dear all, I am new to R and statistics really in general. I am hoping that someone will be able to point me in the right direction and/or suggest a technique/package/reference that will help me with the following. I have: Some input variables (integers, real) Some output variables (integers, real) and I want to find out which between the two correlate best - i.e. the salient features. I

Hey, I''m experiencing strange problem: non-deterministic PV domain hang, only on some machines (with fast SSD drive). I''ve tried xen-4.1.0 and xen-4.1.1 with many kernels different kernels: VM: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.0.3 - vanilla 3.1 rc2 dom0: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.1 rc2 Result always the same: sometimes VM

Anyone have much luck with these on ATA's? I have a few sites that use them succesfully with multi-port Audiocodes boxes, but just connected ten machines to Linksys 2102s and they are very flaky. Using u-law on a 100Mb switched network that is barely utilized, then out a T1 on a Sangoma card. Perhaps there is some tuning on the Linksys or the credit card machine itself? Going to look

Following problem: Say you have a bunch of parameters and want to produce results for all combinations of those: height<-c("high","low") width<-c("slim","wide") then what i used to do was something like this: l<-list() for(h in height){ l[[h]]<-list() for(w in width){ l[[h]][[w]] <- doSomething() } } Now those parameters aren't

CPUIDLE: Avoid remnant LAPIC timer intr while force hpetbroadcast LAPIC will stop during C3, and resume to work after exit from C3. Considering below case: The LAPIC timer was programmed to expire after 1000us, but CPU enter C3 after 100us and exit C3 at 9xxus. 0us: reprogram_timer(1000us) 100us: entry C3, LAPIC timer stop 9xxus: exit C3 due to unexpected event, LAPIC timer continue running
