I referred in my reply to a paper by Diaconis and Sturmfels. The exact reference is: Diaconis and Sturmfels, Algebraic algorithms for sampling from conditional distributions, Ann. Stat 26 (1998) 363-397. They cite the following: Besag and Clifford, Generalized Monte Carlo significance tests, Biometrika 76 (1989) 633-42. which actually co...

Dear list, I get the following message while computing truehist in R 1.4.1 on Redhat Linux 7.1: > truehist(lsk$Pox, nbins = "FD" , prob = TRUE, xlab = "Pox [mmol/kg]") Error in switch(casefold(nbins), scott = nclass.scott(data), "freedman-diaconis" = , : couldn't find function "nclass.fd" Maybe the "nclass.fd" should be changed into "nclass.FD"? But I could not find it in the directories. Regards, Ulrich -- __________________________________________________ Ulrich Leopold MSc. Departm...

I'm looking at algorithms for determining coincidences. In educational testing, it is interesting to look at cheating via the birthday problem where I can assess the probability of n students having the same test score in a class of size k. I was writing my own code for the b-day problem until I ran into the qbirthday() function, which has solutions for the overflow problems I kept running

Hi R-Devel, The Sage project (http://www.sagemath.org) has been working extremely hard for several years to create a viable free open source alternative to Maple, Matlab, Mathematica, and Magma. Numerous users have requested statistical functionality. Though Sage includes scipy and numpy, which have some statistical functionality, we've decided the best longterm solution is to strongly

Hi, I tried to calculate the formula for the birthday problem (the probability that at least two people out of a group of n people share the same birthday) But the factorial-function allows me only to calculate factorials up to 170. So is there a way to push that limit? to solve this formula: (factorial(365) / factorial((365-23))) / (365^23) (n=23)

My name is Michela Marignani and I'm an ecologist trying to solve a problem linked to knight' s tour algorithm. I need a program to create random matrices with presence/absence (i.e. 1,0 values), with defined colums and rows sums, to create null models for statistical comparison of species distribution phenomena. I've seen on the web many solutions of the problem, but none provides

Hi I have two datasets, A and B, consisting of two columns of numbers representing x and y coordinates. They have 10 and 6 rows respectively. I want to plot two scattergraphs, one above the other. The lower graph to contain A (10 points) and the upper graph to contain B (six points). The x-axes of the two graphs must line up. I then want to draw straight lines that connect points of B to a
