Dear all, I have a question on how to set up the starting model in POLYCLASS and make sure the terms in the starting model retained in the final POLYCLASS model. In the function POLYMARS, this can be done using the STARTMODEL option. See below for example, I started with model y= b0 + b1*X1 + b2*X2 + b3*X4 + b4*X5 + b5*X2*X5 + e > m00 <- matrix(c( 1, NA, 0, NA, 1, 2,

Friends, I changed one line of a package at the source level and then rebuilt it.

I've seen references to "polymars", an R implementation of Friedman's MARS algorithm. Can anyone tell me where I might be able to find this (doesn't seem to be in the contributed packages.

Does the polymars library exist anymore?

I was able to hack the code in the polspline package in order to change the plot.polymars function so that I can set the limits of my y-axis. However, I was only able to do this by entering plot.polymars in R, copying the code to Word, changing what I needed, and then pasting the new code in R to redefine the polt.polymars function. I was able to successfully change the function, but now I would

Hi.., is there a function in R to fit bivariate splines ? I came across 'polymars' (POLSPLINE) and 'mars' (mda) packages. Are these the one to use or are there other specific commands? Thanks. Harsh

Hi everyone: Polyclass is a polytomous logistic regression model using linear splines and their tensor products. It provides estimates for conditional class probabilities which can then be used to predict class labels. I know there is Polyclass package in S-plus. So I'm wondering if there is a corresponding package in R? I have been searching for it for quite a while, but still

Hi All, I can't quite figure out how to change the parameters of the x and y axes when I plot a polymars object. I want to add a scatterplot of the data points, but the polymars plot seems to automatically set the parameters to fit the polymars line. I've tried using plot(poly,1,fig= c(x1,x2,y1,y2)) but have no luck. Any thoughts? Thanks, Ryan

Dear R friends- I'm attempting to generate a regression tree with one gradient predictor and multiple responses, trying to test if change in size (turtle.data$Clength) acts as a single predictor of ten multiple diet taxa abundances (prey.data) Neither rpart or mvpart seem to allow me to do multiple responses.

Dear All; I have used fbmSim to simulate a fbm sequence, however, when I tried to estimate the Hurst effect, none of the nine procedures gave me an answer close enough to the real value, which is 0.5 (n=1000). So, would you please advice, 1. which is the best method to estimate the H among the 9 mehods, R/S, higuchi or Whittle? 2. how to choose the levels (default=50), minnpts, cutoff values or

Hello, Apologies if this question has already arised, hope you can help me to the find the solution to this or point the place to look at. I have a multidimensional piece-wise regression linear problem, i.e. to find not only the regression coefficients for each "interval" but also the beginning and ends of the intervals. To simplify it to the one dimensional case and two intervals,

Can you help me interpret the output I get with "polymars"? I'd like to find a regression model to predict 2 dependent variables (then called Y1 and Y2) with 2 independent variables (then called X1 and X2). Here is the output: polymars(responses = data[, 13:14], predictors = data[, 2:3]) Model fitting 0/1 size RSS 1 RSS 2 GCV 1 1 1 0.2486744

Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

Hello all, I'm trying to find out how to perform a 'segmented regression'. I have some data and the 'classical' model used is: y(t) = a + bx(t) + cx(t)^2 + u(t) for x(t) < x(0) y(t) = a + bx(0) + cx(0)^2 + d(x(t) - x(0)) + u(t) for x(t) > x(0) and u(t) = rho.u(t-1) + eps (It's a model using an ARIMA-model, in this case AR(1)-process) The parameters to estimate here

Hello R Community, I am really impressed by the 'R'. I am a computer engineer. Further, I have done work on Linux Code at my home and Worked on Cisco IOS platform.

If anybody can tell me the way then please show me the way. I

Hi there, Does R has built-in codes for nonpara. bivariate regression so that I can estimate the joint distribution of two variables as a function of some covariates?

My problem is the following : I create 2 zoo objects and then I try to subset one of them using logic. indicesthatpass is a vector of trues and falses but when I send it into bckret, it returns an empty bckret. Obviously it has something to do with bckret being a zoo object and if I do the same subsctripting off of coredata(bckret), I'm confident it will work. But, I need to keep the minute
