similar to: [newbie] how to do a 3d plot of bivariate density?

Hi all, I'm looking to add a "density" smoother on top of a hist when Freq=T. In order to do this I can use the relation between count and density, but I would like to know if there is a way for me to predict it upfront. Here is an example: set.seed(242) z = rnorm(30) hist_z <- hist(z) hist_z$counts / hist_z$density # the relation is 15 # why is this 15 ?? # So I can now do:

Dear R users, I would like to plot the bivariate density surface with its marginal densities on the sides of the 3D box, just like in the picture I attach. I tried to found information about how to do it but did not find anything. Does anyone know how to do it? Thanks in advance, Eduardo.

Am trying to do some study on bivariate binomial distribution. Anyone knows if there is package in R that I can use to calculate the density function of bivariate binomial distribution and to generate random samples of it.

Hi, I am using the KernSmooth package to estimate nonparametrically bivariate density functions. However, it seems that the bandwidths (one for each co-ordinate direction) have to be selected manually. This does not apply for the univariate case, for which dpik (included in KernSmooth) uses up-to-date plug-in rules. Does anyone know about a package, or function, which estimates bandwidths

Is there code for bivariate kernel density estimation? For bivariate kernels there is kde2d in MASS kde2d.g in GRASS KernSur in GenKern (list probably incomplete) but none of them seems to accept a weight parameter (like density does since R 2.2.0) -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at

Dear R-Users I would like to estimate a constrained bivariate normal density, the constraint being that the means are of equal magnitude but of opposite signs. So I need to estimate four parameters: mu (meanvector (mu,-mu)) sigma_1 and sigma_2 (two sd deviations) rho (correlation coefficient) I have looked at several packages, including Gaussian mixture models in Mclust, but I am not sure

You can try `locfit', though it does local likelihood, rather than garden-variety kernel density estimation. Here's an example: library(locfit) data(cldem) den.fit <- locfit(~ x1 + x2, data=cltrain) predict(den.fit, newdata=cltrain) Andy From: Strickland, Matthew > > Hi, > > My data consists of a set of point locations (x,y). > > I would like to know if there

Hi Spencer, I have seen your name on the web site, and perhaps you can help me with my R problem. I'm trying to use KernSur to put in evidence a substructure in a bidimensional plot. My problem is that, in order to get the density in the low density areas (in which the substructure is located) I should use different bandwidths. How I can do that? Also, I think that the best choice for my

Hi list, I could'nt find specific info ion the subject on google, and I'm not sure if the list is appropriated, but, I need to migrate a complete directory-tree from one w2k server to 1st another w2kserver, an then, to a Samba Server (still to be installed). The biggest problem is, if I just copy the directory, I will loose all info over users and permissions. I will also loose the

Hi, there. Suppose I have a bivarariate data matrix y1 and y2. I want to plot a 3-D picture of the estimated density f(y1, y2) against y1 and y2? How can I do that? Do I use persp() or density()?

I've been trying to implement bivariate kernel density estimation. For data like mine, function "kde" from package "ks" with bandwidth matrix derived by function "Hscv" seems like a very good choice. Unfortunately, Hscv seems unmanageably slow except for very small sample sizes (up to a few hundred) and my sample sizes are quite large (up to a few thousand).

Dear R users: I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to get a estimated bivariate density and corresponding plots as follows: new.data.normal<-data.normal[!is.na(data.normal[,2]),] x<-new.data.normal[,2] y<-new.data.normal[,3] op <- KernSur(x,y, xgridsize=50, ygridsize=50,

Hye every one, My question will certainly seem stupid as I am quite a beginner in R. I would like to trace a curve which fits these two vectors: x<-c( 2,3,4,5,6,7,8,10 ) y<-c( 20, 12, 8, 6, 5, 4.5, 4, 3.8) It seems to follow a non linear model. Could anyone help me because I could'nt find the answer I am looking for in the FAQs. In advance thank you for your time. G. Lefebvre

Hi all, I am new in Dovecot. I wanna use Dovecot in the big mail system about 4 million active or passive users. We use recently Courier Imap, but search mails process is so slowly. I tried Dovecot that it is better then Courier so much. But I have a problem with integration Dovecot to my system. I am using some extra flags in mails to mark them from others. For example I use a private flag
