similar to: problem understanding the result of pnorm2d()

I submitted this to rmetrics help list as well... I've been using R-2.4 with Rmetrics successfuly for a year or two. I recently moved to Ubuntu Linux 8.04, loaded R via apt-get install R-base etc. etc... then in the R interface i ran install.packages("fMultivar"), chose the CRAN mirror and it loaded fMultivar and all the required dependecies. However, when I try to run the same

Hola Alguien me podría decir como hacer una grafica del tipo persp() de la densidad de una distribucion normal bivariante estandarzada con correlacion 0.5?? gracias [[alternative HTML version deleted]]

Dear all, In the x-axis of a xyplot I define dates ,for example 01-10-2007 instead of numbers, in a range of 77 days. I would like in my output to have the whole date as a point. When I plot it, then the output is a big mess! I can not distinguish anything; the result is a thick, black line of overlapping dates. Is there any solution so I can really distinguish and see clearly the dates in the

Dear all, I have a simple (I think) question that is troubling me lately: Is there any main difference between anova() command and aov() command when performing an ANOVA in Experimental design analyses? Thank you for your time, Ismini

Dear R users a problem I encountered while installing fMultivar, I would appriciate any help with this. > install.packages ("fMultivar", dependencies=TRUE) Warning in install.packages("fMultivar", dependencies = TRUE) : argument 'lib' is missing: using /usr/local/lib/R/site-library also installing the dependencies 'fBasics',

Hi, I tried to install fMultivar package but an error occurs that I could not understand.

Hi folks! Does anybody know how to use the OLS function in fMultivar to do dynamic regression? I've tried specifying lags in OLS using a data series created in fSeries and it doesn't seem to work. I've done dynamic regression using dyn$lm and I was wondering how to accomplish the same thing using the OLS function from fMultivar. Thanks! John [[alternative HTML version

Hello, I would like to use the function EWMA() in the fMultivar Package and I have a series of data x, which is the returns series. Basically, I would like to get the variance estimation using EWMA. I am trying something like EWMA(x, lambda) and I have a couple of questions: Should x be the returns series or price series in my case? When I get the result, there are the same numbers of data

Hi All, I have a netcdf gridded file with LCC projection. I can easily use image.plot to visualize it. However, as the axises are in X,Y, not Lat and Lon, I could not add state or country maps onto it (or lat lon information). I do have a grid2d file that describes the lat and lon for each (X,Y) grid, but the lat and lon are not regularly spaced, so I could not use image.plot. Does anyone know

Dear list, Is there a way to reorder the xaxis using lattice. Using the following data, the x-axis is ordered as BP GH MH PF RE RP SF VT but I would like the x-axis to be ordered as PF RP BP GH VT SF RE MH.

Using a more stable nonlinear modeling tool will also help, but key is to get the periodicity right. y=c(16.82, 16.72, 16.63, 16.47, 16.84, 16.25, 16.15, 16.83, 17.41, 17.67, 17.62, 17.81, 17.91, 17.85, 17.70, 17.67, 17.45, 17.58, 16.99, 17.10) t=c(7, 37, 58, 79, 96, 110, 114, 127, 146, 156, 161, 169, 176, 182, 190, 197, 209, 218, 232, 240) lidata <- data.frame(y=y, t=t) #I use the

Dear list members, I would like to create two series of plotted mean values and error bars, yet with different locations along the x-axis. Plotting of first series using plotCI with the standard arguments goes without any problem. However I do not succeed to add the second series in the same plot, which should be horizontally shifted from the first series along the x-axis. The “add=TRUE”

To R community: I've been pulling my hair for the past few days over this issue now, and I may be at the point where I just can't spot my error. So I thought to reach out to the community and hope someone could kindly help me. I'm trying to create a correlation matrix and plot it. However, I'm trying to create a hybrid of correlation matrix from two different periods, say

Hola, Aunque un poco más elaborado, el resultado me parece más limpio (adjunto gráfico). He utilizado gran parte del código de "pepecb". Por otro lado (Neo) es recomendable que cuando incluyas una duda en la lista des también referencia de su sesión (comando de R: sesionInfo). La función que usas "xYplot()" es del paquete "Hmisc" y aunque está basada en el paquete

Dear all, I have a bivariate dataset from a preliminary study. I want to do two things: (1) estimate the probability density of this bivariate distribution using some nonparametric method (kernel, spline etc); (2) sample a big dataset from this bivariate distribution for a simulation study. Is there any good method or package I can use in R for my work? I don?t want parametric models like

Dear users I am reposting this and hope it will be accepted this time. I am using copula package to fit my bivariate data and simulation. As explained in package documentation we can use our own data distribution to feed on copula as long as we have d, p and q (pdf, cdf and quantile) functions are available. Hence my code for those are: # Make the functions for data distribution

This might not be the correct forum for this question for there might be some flaws in my logic so the R function I'm looking for might not be the correct, but I know there?s a lot of smart people in this forum so please correct me if I'm wrong. I have been googling and searching in this forum for something useful but so far I'm out of luck. This is the background to my problem. I
