search for: multiway

dear all, in the package pwr , there is the fonction power.anova.test which permit to obtain the power for a one-way ANOVA...but I'm looking for a way to compute the power of a multiway ANOVA.( find the 1-beta). Is it possible? do you have some ideas ? regards [[alternative HTML version deleted]]

Hi, does anyone know of a function to calculate odds ratios in multiway tables (stratified) (+ the other usual statistics involved) i mean: say we have a table r*c*d, For every d (depth) we have a r*c table, and in this table the odds ratio's are calculated for every 2*2 subtable in it. logically this function would look like): ORs(multiwaytable) or ORs(data$var1...

R has amazing capabilities, but percentage tables are a weak spot IMHO. There's prop.table but that's rather unwieldly, especially for multiway tables. CrossTable by Marc Schwartz in the gregmisc library makes percentage tables a breeze but is limited to two-way tables. So I decided to try my own hand at writing an R-function that would make it easy to produce nicely formatted percentage tables for one-way, two-way, or multi-way tables. T...

PTAk_1.1-1 ( Principal Tensor Analysis on k modes) has been released on CRAN A multiway method to decompose a tensor (array) of any order, as a generalisation of SVD also supporting non-identity metrics and penalisations. 2-way SVD with these extensions is also available. The package includes also some other multiway methods: PCAn (Tucker-n) and...

...ecompiler. I was wondering if some of LLVM could be used for a decompiler. There are several stages in the decompiler process. 1) Take binary and create a higher level representation of it. Like RTL. 2) The output is then broken into blocks or nodes, each block ends in a CALL, JMP, RET, or 2-way or multiway conditional JMP. 3) The blocks or nodes are then analyzed for structure in order to extract loop information and if...then...else information. 4) Once structure is obtained, data types can be analyzed. 5) Lastly, source code is output in C or C++ or whatever is needed. I was wondering if LLVM coul...

It has long been a nuisance to me not being able to form margins on multiway tables in a simple fashion, so i wrote margins(). In my opinion it should go into the base package. The code and the documentation is in: http://www.biostat.ku.dk/~bxc/R/margins/ Please help yourself, and enhance and rename as you see fit. Bendix ---------------------- Bendix Carstensen Senior...

I'm not sure that there's anything that will help you with this step for LLVM. The closest I can think of is Qemu, and I think that uses dynamic binary translation (i.e., you have to run the binary program). > 3) The blocks or nodes are then analyzed for structure i...

I am trying to create a dendrogram object to be able to display a multiway table. I understand how the dendrogram object is structured, a nested list of lists, but I am having trouble trying to create that structure from a table. Basically, what I would like to do is pass a multiway table, say table(a,b,c) to a function and have it display the table as a dendrogram. If...

I wrote some functions for multiway CANDECOMP, i.e. for least squares fitting of a_{i_1\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^1_{i_1s}\cdots x^m_{i_ms} with arrays of arbitrary dimension. Reminded me of the good old APL days. I could not find this in the archives, but if it's already there, I would appreciate if someone l...

Hello, can someone tell me how to extract a partial table from a multiway table? Something else: I tried to do basic operations on cross-tables, like subtracting two cross tables with same dimensions and i was unable to do so. Is there another way? thanks! __________________________________________________________

I would like to add points to a wireframe but with a conditioning variable. I found a solution for this without a conditioning variable here, http://finzi.psych.upenn.edu/R/Rhelp02a/archive/65321.html. Does anyone know how to plot a wireframe conditioned on a variable and add the points conditioned on the same variable, similar to the solution at the link above?

Hi, I was wondering if there is a direct approach for lining up 2-column matrices according to the values of the first column. An example and a brute-force approach is given below: x <- cbind(1:10, runif(10)) y <- cbind(5:14, runif(10)) z <- cbind((-4):5, runif(10)) xx <- seq( min(c(x[,1],y[,1],z[,1])), max(c(x[,1],y[,1],z[,1])), 1) w <- cbind(xx, matrix(rep(0, 3*length(xx)),

I've put two packages for R on my home page at http://www.xs4all.nl/~jhckx/R/. The "pcnt" package is for multiway percentage tables. I've posted a first effort called "ctab" on this group and a request for enhancing "ftable" with percentages on the wishlist. The "mcl" package is for estimating multinomial logistic models using conditional logistic regression. This gives great...

Hi helpeRs. When I do two-ways tables dimnames in columns are almost left-adjusted: <- factor(rbinom(30,1,.3),labels=c("first","second")) > b <- a > table(a,b) b a first second first 21 0 second 0 9 If I do a oneway table however, dimnames are right-adjusted: table(a) a first second 21 9 Actually I must admit I

Greetings, I've just put out the latest version of "The Popularity of Data Analysis Software" at http://r4stats.com/popularity. This update includes complete data for 2010, the addition of number of blogs for each software, more coverage of Statistica, and, where possible, measures regarding the implementations of the SAS Language: Carolina and the World Programming System (WPS).

...ls, multidimensional Rasch models). Status: partly done. -- lssem package (linear structural equation models with latent variables, reformulated as matrix decomposition problems, and solved by majorizing least squares loss functions). Status: planning stage. -- threeway package (multiway generalizations of principal component analysis with various constraints on the decomposition). Status: on the horizon. All of this is currently in straightforward R, without any compiled C code, and without any OOP. The idea is that eventually these will be nicely organized in R packag...
