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.

Hello forum, I want to find in survey how to test V-cramer and coefficient Goodman-Kruskal gamma, to test the collinearity between varibles to enter a model. For the V-Cramer function is used with the package vcd assocstats but without considering the survey package. I appreciate the cooperation. Att. Diana Martinez [[alternative HTML ver...

Dear R-Users, I need functions to calculate Yule's Y or Cram?rs Index, in order to correlate variables that are nominally scaled? Am I wrong? Are such functions existing? Sincerely, Timo

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 t...

I simulate a uniform data and then transformed into Burr(1,3,1) data, which is of pdf: f(x)=[3*(x^2)] / [(1+x^3)^2], x>0 How can I perform a goodness-of-fit test (k-s, anderson-darling,chisq,cramer-von mises,...) on it (should highly accept) to get test-statistics & p-values?

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.

...d a Thomas 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 assistanc...

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]]

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...

...ding to (2) (which is not yet published or I'd cite it), -1 T Dcv(x,y) = sqrt( Dh(x,y).C .Dh(x,y) ) where x and y are rows of the same data frame, Dh(x,y) = ifelse(x == y, 0, 1) (so that sum(Dh(x,y)) is Hamming distance), C is the matrix of Cramer's V scores between the columns of the data frame. This is an analogue of Mahalanobis distance, with C playing the role of the variance-covariance matrix. I wanted to try this out, so I wrote some R code. In particular, I couldn't persuade myself that Dcv(x,y) was always defined. Wh...

I'd also like to plot the curves for both sets of values. Could anyone help me with these two points? Many thanks, Andrew Wilson

...ng function. 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 pr...

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

Greetings. For R gurus this may be a no brainer, but I could not find pointers to efficient computation of this beast in past help files. Background - I wish to implement a Cramer-von Mises type test statistic which involves double sums of max(X_i,Y_j) where X and Y are vectors of differing length. I am currently using ifelse pointwise in a vector, but have a nagging suspicion that there is a more efficient way to do this. Basically, I require three sums: sum1: \sum_i\sum_...
