Off topic: nonparametric regression
Hi All,
What do you consider to be the best book(reference) on nonparametric regression?
I am currently reading the book of Kunio Takezawa(2006): "Introduction to nonparametric regression".
Is the book of Hardle(1990): "Applied nonparametric regression" better? or maybe another book?
This is off topic, but most of the books is using R or S-plus.
Thanks

multivariate nonparametric regression with e >= 0
Hello all,
I'm a relatively new user of R, having mostly used it only for plotting so
far. I'm also not very familiar with regression methods, hence forgive my
greenness on the topic.
What I want to do in R is multivariate nonparametric regression, with a slight
hitch. From my experimental data I have a multitude of samples whose values
approximate a function `f' that is defined

Calculation time of isoMDS and the optimal number of dimensions
Dear all,
I'm running a set of nonparametric MDS analyses, using a wrapper for isoMDS,
on a 800x800 distance matrix. I noticed that setting the parameter k to
larger numbers seriously increases the calculation time. Actually, with k=10
it calculates already longer than for k=2 and k=5 together. It's now
calculating for 6 hours, and counting...
There is quite a difference between the

How to use formulas for multivariate clustered data?
Dear R experts,
I wrote already a couple of weeks ago but did not get any reply.
Therefore I'll rephrase my question and hope some of you can give me
some answers or some advice where better to look for an answer.
In general I'm looking for information on how to program functions
using formulas in order to write a nonparametric multivariate
regression function with possible

Sir,
I want to draw random from any multivariate disrtibution. Is there any
function in R to do this?

simulating data from a multivariate dist
Sir,
I am working on fitting distribution on multivariate financial data and then
simulate observations from that fitted distribution. I use stepAIC.ghyp()
function of 'ghyp' library which select the best fitted distribution from
generalized hyperbolic distribution class on the given dataset.

Nonparametric k-way ANOVA
Sorry if this subject has been already dealt here.
Which are some common tests for nonparametric k-way ANOVA?
I have read about Kruskal-Wallis test as a kind of nonparametric one-way
ANOVA, but I have not found anything about a general-setting (I mean k-way)
nonparametric ANOVA.
Can you recommend me a good R package (or other reliable software) for that?
Looking forward to your answers,

nonparametric logistic regression based on locally weighted scatterplot smoothing (lowess)
Dear UseRs:
Recently, I have read an article regarding the association between age and
lymph node metastases.
http://jco.ascopubs.org/content/27/18/2931.long
In statistical analysis, the authors stated "Because a nonlinear
relationship between age and lymph node involvement was expected based on
existing literature, lymph node involvement was also regressed on age using

nonparametric mixed effect model
Hi all,
I'd like to compare species richness patterns of two groups with paired
observations with an extra continuous fixed effect as a covariate. Normally
I would use a standard general mixed effect model for such data, with one
group variable and a continuous variable as fixed effects, plus a random
effect for the paired observations. However, after making such a model with
the lme

Nonparametric Effect size indices
Hello!
For comparing two non-normally distributed samples, Leech (2002) suggested
to report nonparametric effect size indices, such as Vargha & Delaney's A or
Cliff's d. I tried to search the R-sites, but could not find related
procedures or packages that include nonparametric effect sizes.
Thank you for your help!

New package `np' - nonparametric kernel smoothing methods for mixed datatypes
Dear R users,
A new package titled `np' is now available from CRAN.
The package implements recently developed kernel methods that seamlessly
handle the mix of continuous, unordered, and ordered factor datatypes
often found in applied settings.
The package also allows users to create their own
nonparametric/semiparametric routines using high-level function calls
(via the function npksum())

R2HTML problem
Im developing an application with R and Gtk+. It's just a simple GUI which
helps new users to interactuate with R. Thing is, when you do a statistical
analysis, I also want to provide a HTML report, but HTMLStart doesnt work
propperly when executing from TinnR. It does create the file but not empty,
I've tried some examples from different websites, and it's always the same..

Nonparametric manova
Hi, I have seen a discussion in the R-help asking whether nonparametric
manova has been implemented in R yet. This discussion is form March 2006 and
there seemed to be no package or function implemented at the time. Has this
changed? Is there a package that provides nonparametric manova as in McArdle
and Anderson (2001) and Anderson (2001) now?
Thanks,
Daniel

Non-crossing Nonparametric quantile regressions
I've been looking for ways to calculate a large number (100) of non-crossing
Nonparametric quantile regressions on large populations (1000+).
Can the quantreg package in R ensure the non-crossing property?
If not, do you know any alternative?
Thank you,

Nonparametric generalization of ANOVA
My interpretation of the relation between 1-way ANOVA and Wilcoxon's
test (wilcox.test() in R) is the following.
1-way ANOVA is to test if two or multiple distributions are the same,
assuming all the distributions are normal and have equal variances.
Wilcoxon's test is to test two distributions are the same without
assuming what their distributions are.
In this sense, I'm wondering

Nonparametric analysis of repeated measurements data with sm library
Dear all,
Does anybody know how to get more evaluation points in performing Nonparametric analysis of repeated measurements data with "sm" library. The following command gives the estimation for 50 points, by I would like to increase to 100 points
But I do not know how to do that.

Nonparametric Tukey-type multiple comparisons "Nemenyi" test
I am trying to do a Nonparametric Tukey-type multiple comparison
post-hoc test to determine which groups are significantly different. I
have read the dialogue on this topic from the R-help, and am still not
clear why no statistical packages include this test as an option? Is it
not an appropriate test to conduct on non-normally distributed data? Is
the only option to calculate it by hand

nonparametric 2way repeated-measures anova
Dear useRs
is there any nonparametric test for the analysis of variance in a design
with two within-factors (repeated measures on both factors)? Friedman is not
appropriate here, therefore I am grateful for any alternative test.
thanks for any hint
cheers

any function for monotone nonparametric regression?
I am wondering if there is any package in R that can fit a nonparametric regression model with monotone constraints on the fitted results.
