Hi, I wonder if anyone knows a study dealing with the minimum valid number of observations when using CART?. On top of that, when using RandomForest, is it possible to obtained a interpretable tree model as the graphical output of the analysis, just like in "rpart"? Thanks a lot in advance Javier Lozano Universidad de Le?n Spain

Hi R-helpers, Can some one tell me how to train 'mynn' of this type?: mynn <- nnet(y ~ x1 + ..+ x8, data = lgist, size = 2, rang = 0.1, decay = 5e-4, maxit = 200) I assume that this nn is untrained, and to train I have to split the original data into train:test data set, do leave-one-out refitting to refine the weights (please straighten this up if I was wrong). I just don't know

Hello R users, I am trying to run a model with a binary response variable (nesting success: 0 failure, 1 success) and 8 fixed terms. Nesting success was examined in 72 cases in 34 territories (TER) during a 6 study years. Territories are nested within 14 patches (PATCH). I want to run a model taking into account these nested factors and repeated observation. To do this, I assume that the best

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. Sorry for sending this question twice, but I would really like to know your opinion on this topic. I have been reading about the (in)convenience of using least-squares means (a. k. a. adjusted means) in multiple comparisons (I used to resort to them when using SAS). I even read a post in this list warning against them, but not giving much detail.

Hi all, I am trying to detect association between a covariate and a disease outcome using R. This covariate shows time-varying effect, I add a time-covariate interaction item to build Cox model as follows: COX <- coxph(as.formula("Surv(TIME,outcome)~eGFR_BASE+eGFR_BASE:TIME"),ori.data); coef exp(coef) e(coef) z p eGFR_BASE

Hi! I am starting to use the R system. Till now I have been using SAS and SPSS, as my university and department has licences of them. I would like to know if there is a mail list in Spanish (this is my native language), and if there is some kind of tutorial specially oriented to people used to work with SAS or SPSS who want to migrate to R. Thank you! Felipe
