Hall all, Where can I find the two sample Cramer-von Mises test in R package? Thank you. Legendy -- View this message in context: http://www.nabble.com/Two-sample-Cramer-von-Mises-test-tp20174229p20174229.html Sent from the R help mailing list archive at Nabble.com.

Hi all, I'm curious if anyone has coded an Expectation-Maximization algorithm that could help me model some circular data I have. I'd like to model it as a mixture of uniform and Von Mises centered on 0, so the only free parameters is the mixing proportion and the kappa of the Von Mises. I couldn't find anything in the contributed packages that seemed to suit this purpose. Any pointers would be greatly appreciated! Cheers, Mike -- Mike Lawrence Graduate Student Department of...

Hi, this is my first help request so please bear with me. I've been running some normality tests using the nortest package. For some of my datasets the Cramer-von Mises normality test generates an extremely high probability (e.g., 1.637e+31) and indicates normality when the other tests do not. Is there something I'm misunderstanding or potentially a bug in the code? Below are the results of the tests and then, below that, I've provided that column...

Dear all, I would like to fit a von mises mixture to my data using the EM Algorithm. Unfornately, existing packages (including circstats) doesn't provide such method. So, does anybody have written such code ? Big thanks, Christophe, (R newbie)

Dear All, I has posted this question on friday. I am trying to plot von Mises density on the circle. One can use dvm function from the CircStats package, by giving a set of angles, mu and kappa to plot the circular density on the line. Does any one have a macro that does it on the circle? These plots are displayed in Nick Fisher's book. Any help will be appreciated. Th...

Hello list, Is there any function in some package can calculate two sample Cramer-von Mises test statistic? I searched around and only find one sample version cvm.test() in nortest package. thanks, WC _________________________________________________________________ Don’t just search. Find.

...process based on pair-correlation function. I know the function "pcfinhom" is available to characterize the IPP, but I have no idea about how to use the pcf with Thomas process? Additionally, generating simulation envelopes using these two null models is another problem for me. Cramer-von Mises (CvM) can assess the curve-wise significance of deviations from null hypothese, but in the spatstat package, is there any functions can do this work? I am not very familiar with R, so my problem might be simple. I hope anyone have any experience with these work can give me any assistance. Many t...

Hi all, When I detect the spatial point pattern, I want to use the Cramer-von Mises statistic to assess the curve-wise significance of deviations from null hypotheses. Who can tell me which function in R package "Spatstat" can do this work? Thanks a lot Jeff [[alternative HTML version deleted]]

Another fortnight, another Winetricks. This release fixes a handful of bugs, and adds a handful of games (or, really, ports them from wisotool). It also brings back the old verb dotnet20sp2, since that seems to work with wine-1.3.18 (please let me know if it's useful). It also adds a rudimentary gui to prompt for Steam username and password, cleans up the --help message, and improves mac and

I'm wondering if anyone can help me? I'm trying to run Secret of Monkey Island special edition in Steam on wine with Ubuntu Maverick Meerkat. I can install steam and use it to install the game (after it installs directx), apparently with no problems, but when I try to run the game, a window opens saying "Preparing to launch The Secret of Monkey Island: Special Edition".

Hi, ? I'm trying to carry out Cramer von Mises tests between pairs of vectors belonging to a discrete distribution (concretely frequencies from 0 to 200). However, the program crashes in the attempt. The problem seems to be that these vectors only have positive integer numbers (+ zero). When I add a random very small positive decimal to the non...

I have a centos 4.2 32bit app that when installed on centos 4.2 64 bit box and try to run it I get "libxml2.so.2 not found". however if I "rpm -qa | grep libxml2" it shows up just fine. How can I get this app to run on the 64bit box (without recompiling yet). The recompiling will come someday... right now I just would like it to run. Thanks Jerry -------------- next part

Hi, I'm dealing with wind data and I'd like to model their distribution in order to simulate data to fill-in missing values. Wind direction are typically following a vonmises distribution and wind speeds follow a weibull distribution. I'd like to build a joint distribution of directions and speeds as a VonMises-Weibull bivariate distribution. First is this a stupid question? I'm a newbie in statistics and R :) Is it possible to do it in R? Is there a way to...

.... In this function four criterions for choosing distributions. Can we call these criterions as model selection techniques or goodness of fit techniques or both? Because goodness of fit techniques are usually performed after modle selection. Can I found chi-square, kolmogrov-sminov and cramer-von mises tests for testing goodness of fit for proposed distributions?

I believe there to be a bug in the cvm.test module of the nortest package authored by Juergen Gross. I do not know how to contact the author directly. I've been running some normality tests using the nortest package. For some of my datasets the Cramer-von Mises normality test generates an extremely high probability (e.g., 1.637e+31) and indicates normality when the other tests do not. I don't believe the generated probability should exceed a value of "1". Below are the results of the tests and then, below that, I've provided the...

Hi, does anybody know of a nice test to detect trend turning points in time series? Possibly with reference? Thanks, joerg

Hi folks, I have circular data that I'd like to model as a mixture of a uniform and a Von Mises centered on zero. The data are from 2 groups of human participants, where each participant is measured repeatedly within each of several conditions. So, the data frame would look something like: ######## design = expand.grid( person = 1:20 , variable1 = 1:2 , variable2...
