Hi, I have the binned data (observed and generated from model)  that I would like to test using the anderson-darling goodness of fit test.  But I'm not sure which package in R to use. I tried ad.test(...) but it does not recognise the test by Vito Ricci in FITTING DISTRIBUTIONS WITH R   > ad.test(hist_hume_beec[,1],hist_hume_beec[,2]) Error: could not find function "ad.test"

Hi, I'm not a statistician so sorry for possible trivial questions ... I want to perform a GoF test on sample data against several distribution (like Extreme Value, Phase Type, Pareto, ...). Since I suspect a long-tailed behaviour on data I want to use Anderson-Darling (AD) GoF test because it's well known it's more sensible to tail data. Looking at R packages the only AD test is

Hi, I would like to compute a goodness-of-fit statistic for one data series against a t-distribution, and obtain the quantiles of the distribution of the statistic with given degrees of freedom. I wonder if this is implemented in a package. I know that the critical values have to be computed for every distribution, and this requires numerical integration typically. I would prefer if I could get

Hi everyone, I have been long working on a project (http://asterisktools.org, to be released under GPL) that aims to provide desktop tools for Macs. I am finally getting to the release stages of this application and hope to have an early BETA available next weekend. If there is anybody who is interested in this tool, please send me an email as I am looking for people who can test the

Hello R-world, I am facing a peculiar problem and hope someone out there can comment on it. In goodness-of-fit tests for evaluation of distributions, there are three well-known methods: 1. Chi-square 2. Anderson-Darling 3. Kolmogorov-Sminrov I am trying to use the second test. Many researchers have reported results using this test. I wrote programs in C and now in R to do this. I run into

Hace días escribí......creo que se perdió mi mensaje, voy de nuevo con mi pedido de ayuda... Buenas, soy novata en R, estoy comenzando con RCmdr y quisiera saber si pudieran ayudarme dándome algunas pistas para bajar los paquetes que se necesitan para activar muchas de las funciones que aparecen en la pestaña de Análisis y empezar a aplicar algunos análisis. Yo sé que tal vez se dediquen sólo a

Dear All, Is there any modules to compute the chi-square goodness of fit , K.S. statistics and Anderson Darling nonparametric test and compre the fitting of a class of distributions using these tests?

dear experts, i am a novice and have been trying to use the anderson-darling test on a simple text file with one column of data. i have followed the example in the manual to read from a file into a vector(mm). i am able to see the summary stats with >summary(mm) however, when i try to use the ad.test package, it keeps coming up with the following error messages, > ad.test(mm) Error in

Hi, I'm trying to run an anderson-darling test for normality on a given variable 'Y': ad.test(Y) I think I need the 'nortest' package, but since it does not appear in any of the Ubuntu repositories for 2.10.1, I am wondering if it goes by the name of something else now? Thanks -- View this message in context:

Hi Everyone, I am in a fix with an installation for a client where I need PHP version 4.3.10 or above (4.3.x, but not PHP 5). The application we are trying to run will not run on PHP 5. CentOS 4.5 provides PHP 4.3.9, is there a quick an easy way to have PHP 4.3.10 available on either CentOS 4.5 or CentOS 5 Any pointers will be greatly appreciated. -- "I never look back darling, it

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?

Buenas tardes Estoy haciendo un análisis LDA y me gustaría cambiar el nombre de los topics a la hora de visualizarlos y en vez de que se llamen 1,2,3...darles un nombre. ¿Es posible en este código? lda22 <- LDA(reviews_dtm, k = 22, control = list(seed = 1234)) lda22 %>% tidy() %>% group_by(topic) %>% top_n(10, beta) %>% ungroup() %>% mutate(term =

Dear R helpers, I have a bimodal dataset dealing with loss amounts. I have divided this dataset into two with the bounds for the first dataset i.e. dataset-A being 5,000$ to 100,000$ and the dataset-B deals with the losses exceeding 100,000$ i.e. dataset-B is left truncated. I need to fit truncated normal disribution to dataset - I having lower bound of 5000 and upper bound of 100,000. While I

Hello all, Would somebody be kind enough to show me how to do a KS test in R for a lognormal distribution with ESTIMATED parameters. The R function ks.test()says "the parameters specified must be prespecified and not estimated from the data" Is there a way to correct this when one uses estimated data? Regards, Kwabena. -------------------------------------------- Kwabena Adusei-Poku

hello! i don't want to test my sample data for normality, but exponential- lognormal- or gammadistribution. as i've learnt the anderson-darling-test in R is only for normality and i am not supposed to use the kolmogorov-smirnov test of R for parameter estimates from sample data, is that true? can you help me, how to do this anyway! thank you very much! nadja
