hi - in version 2.1 the command >-2^2 gives -4 as the answer. (-2)^2 is evaluated correctly.

Hola a todos, Tengo un pequeño problemilla... Tengo unas 9000 variables que he contrastado con 1 en concreto con el test de wilcoxon. He calculado el p-valor, y queria corregirlo con el permutation-based FDR. He encontrado una funcion con R comp.fdr()que hace esta corrección, pero te pide que le pongas las variables con las observaciones y te hace el test (según he entendido). Yo solo quiero

Dear List, I am not sure how should i optimize a log-likelihood numerically: Here is a Text book example from Statistical Inference by George Casella, 2nd Edition Casella and Berger, Roger L. Berger (2002, pp. 355, ex. 7.4 # 7.2.b): data = x = c(20.0, 23.9, 20.9, 23.8, 25.0, 24.0, 21.7, 23.8, 22.8, 23.1, 23.1, 23.5, 23.0, 23.0) n <- length(x) # likelihood from a 2 parameter Gamma(alpha, beta), both unknown llk = -n*log(gamma(alpha)) - n*al...

Hola, que tal? Tendo una duda, como se puede eliminar una variable de un data.frame? Tambien tengo otra duda, tengo una base de datos importada del spss, donde tengo espacios asignados como missings, pero al pasarlo al R, me coje los espacios como una categoria más. Como los puedo poner como missings? Dolors Giralt _________________________________________________________________ [[elided

...ideas of the book, and notation and concepts are similar to the corresponding R packages that deal with MCMC methods. I have done a search and 2 books seem to satisfy my requirements: - Markov Chain Monte Carlo In Practice, by W.R. Gilks and others. - Monte Carlo Statistical methods, Robert and Casella. What do people think about these books? Is there a suggestion of some other book that could satisfy better my requirements? Thank you very much in advance. -------------------------------------------------------------------------------- The information contained herein is confidential and is...

  Dear R helpers   Suppose I have two sets of ranges (interest rates) as   Range 1 : (7 – 7.50, 7.50 – 8.50, 8.50 – 10.00) with respective probabilities 0.42, 0.22 and 0.36.     Range II : (11-12, 12-14, 14-21) with respective probabilities 0.14, 0.56 and 0.30 respectively.     My problem is to form the combinations of these ranges in a decreasing order of joint probabilities. It is assumed that

I hope this question is sufficiently different from the other requests for book recommendations that it's not repetitious. If not, I apologize in advance. I'm curious what standard reference books working statisticians, or biostatisticians, have within easy reach of their desk.

Dear List, This problem is more a statistic one than a R one. Any one can recommend me some references website or online paper on maximum likelihood estimation?I'm now working on that,while still doubt how to prove that the estimated parameters are normal distributed. Thanks for your time and help! Best, Ning

...x file. Both old and new installations support compressed folder via zlib plugin. If I'm not wrong dsync doesn't support compressed folder, does it? And, if so, are there any chances to have dsync support gzip'ed folders in the (near) future?
