Hi, I wanted to make a transformation with "avas" and "ace" but saw a message " couldn't find function "avas" " what are the possibble reasons of this case? It may be a basic question but unfortunately I am very new in R. Thanks for your helps Regards [[alternative HTML version deleted]]

Hi, Does any one know how we can decide on the correct transformation in (avas and ace) after having drawn the graphs y,g(y) x ,s(x) and g(y) ,s(x) . Is it possible by only looking at patterns the graphs follow for example when y ,g(y) shows a logaritmic pattern can we say that log transform on y is suitable? Thanks for your help.

I am using ACE/AVAS to fit a non-parametric regression model to a multivariate data set. Is there a way to add confidence intervals to the fit and predictions by using bootstrap? Thanks for any suggestions. [[alternative HTML version deleted]]

Hello R helpers! I'm using the avas function form package acepack (called from areg.boot package Hmisc) to estimate automatically transformations of predictors (in this case monotonous) and response. Well, it seems to work quite well, but I have 3 basic questions: - which set of basis functions is used in this procedure? - how do I...

Hello, I would like to perform a monotone transformation of y (my response variable) to achieve additivity. My model is as follows y~X+items I do not want to transform X or items (both of these variables are factors) > X [1] 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 5 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 7 7 7 7 7 7 [61] 7 7 7 8 8 8 8 8 8 8 8 8 Levels: 1 2 3 4 5

Dear ecology fellows, I tried to implement Morisita-Horn distance (instead of Bray that is in the current version) in the code for the Simper analysis in vegan. I would be very grateful if someone can check if the code is right. function (comm, group, ...) { if (any(rowSums(comm, na.rm = TRUE) == 0)) warning("you have empty rows: results may be meaningless")

...a better idea? In an OLS model with just one input variable, a plot will reveal if there is a significant "nonlinearity". One can recode the assigned values to linearize the final model or take the given values and make a nonlinear model. In the R package "acepack" I found avas, which works like a "rubber ruler" and recodes variables in order to make relationships as linear and homoskedastic as possible. I've never seen this used in the social science literature. It works like magic. Take an ugly scatterplot and shazam, out come transformed variables...

Dear R-helpers, I'm learning how to compile R packages with fortran routines and use the acepack source as an example.

This ancient bug was tracked to the acepack library, line 556 in line src/avas.f The troublesome line is: if (x(n).gt.x(1)) go to 30 Since the input arguments are empty, referencing x(1) and x(n) cause a Segmentation fault, and cause R to crash. Acepack author and maintainer Rob Tibshirani <tibs at utstat.toronto.edu> has been contacted with this informat...

...ng on a multivariate linear regression of the form y = Ax. I am seeing a great dispersion of y w.r.t x. For example, the correlations between y and x are very small, even after using some typical transformations like log, power. I tried with simple linear regression, robust regression and ace and avas package in R (or splus). I didn't see an improvement in the fit and predictions over simple linear regression. (I also tried this with transformed variables) I am sure that some of you came across such data. How did you deal with it? Linear regressions are good for the data like y = x + 0.01N...
