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

Our CEO, Dr. Dan Steinberg, is planning to visit Europe in May. He would like the opportunity to introduce statisticians (and statistically minded people) to data mining, data mining applications and to forefront data mining tools. Our algorithms are probably familiar to many statisticians (CART, MARS, MART, TreeNet and RandomForests), although it isn't necessary to be a statistician to

--- included message ---- Thus, my question is: *What common measures exists for ranking/measuring variable importance of participating variables in a CART model? And how can this be computed using R (for example, when using the rpart package)* ---end ---- Consider the following printout from rpart summary(rpart(time ~ age + ph.ecog + pat.karno, data=lung)) Node number 1: 228 observations,

Dear R people, I was recently reading the book `Classification and Regression Trees' by Breiman. This book talks about the CART program. Both Splus and R have implementations of this. However, the book talks about the possibility of extending the existing `standard' set of questions (for continuous variables, these are of the form X < c where X is the variable, c some const) to

According to Dr. Breiman, the RF should be more accurate method than a single tree. However, the performance of each method seems to depend on the proprotion of outcome variable in my case. My data set is a typical classification problem (predict bad guys). When I ran both of them with different proportion of outcome variables(there's a criterion to measure the degree of bad behavior), I

I was under the impression that the tree method (e.g. as implemented in rpart) was insensitive to monotonic transformations of the dependent variable. e.g. Breiman Olshen et al. Classification and Regression Trees state "In a standard data structure [a tree] is invariant under all monotone transformations of individual ordered varaibles" (p. 57) However, I get very different results

Hello. I have a hudge problem, don't know how to deal with it... I'm supposed to implement a tree structure in R, without using rpart library... I don't have any clue about appropriate approach... Anyway, I can't use pointers under R...so how to to it? lists, vectors... Anyway, does anybody knows how the regression tree in rpart was implemented... Someone please help! Thanks, ana

Hi, Is here anyone knows the difference between rapart and bagging when grow a CART tree? Thanks Qin

We are organizing three projects to honor Leo Breiman this year. First, Salford Systems' Data Mining Conference will open with a special session devoted to his scientific contributions. Second, we would like to construct Leo's scientific "family tree," identifying Leo's students, collaborators, and others whose work has been influenced in an important way by Leo's

I have a data set w/ an ordinal response taking on one of 10 categories. I am considering using polr to fit a cumulative logits model. I previously fit the model in SAS (using proc logistic) which provides a test for the proportional odds assumption (p < 0.001 for the test). Are there simple diagnostic plots that can be used to look at the validity of this assumption and possibly help w/

Dear R-helpers, I had a conversation with a guy working in a "business intelligence" department at a major Spanish bank. They rely on recursive partitioning methods to rank customers according to certain criteria. They use both SAS EM and Salford Systems' CART. I have used package R part in the past, but I could not provide any kind of feature comparison or the like as I have no

Our CEO, Dr. Dan Steinberg, is planning to visit Germany in September. He would like the opportunity to introduce statisticians (and statistically minded people) to data mining, data mining applications and to forefront data mining tools. Our algorithms are probably familiar to many statisticians (CART, MARS and MART), although it isn't necessary to be a statistician to use our tools. We

I'm interested in further understanding the differences in using many classification trees to improve classification rates. I'm also interested in finding out what I can do in R and which methods will allow prediction. Can anybody point me to a citation or discussion? Specifically, I want to classify remotely sensed imagery where training data is extracted on class membership by the user.

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart
