Dear All, In a package, I want to use PCA function. The structure I used follow this page: http://www.statmethods.net/advstats/factor.html. fit<-principle(mydata, nfactors=9, rotation=TRUE) or: result<-PCA(mydata) But I don't known why R language in my computer noticed: "not found principle", "not found PCA". I download and installed R-2.6.2-win32.exe. Thanks alot for answering me. Hue University, VietNam. --...

Dear all: I try to analyse a dataset which contain one binary response variable and serveral predict variables, but multiple colinear problem exists in my dataset, some paper suggest that logistic regression for principle components is suit for these noise data, but i only find R can done principle component regression using "pls" package, is there any package that can do the task i need - logistic regression based on principle components, if not, can anyone give some suggestion about how to use R to do m...

Dear all, Can anyone point me to a package that can perform Common principle components? Thank you. Jos?? P. Granadeiro

Setting: 200 input variables, 1 binary target variable. Run a principle component analysis on the data then use the output of the principle component analysis (the generated factors) as input into a neural network -but first having partitioned the pca data into training and testing sets so that a neural network model can be trained on the first partition and tested on...

Hi everyone, I'm not clear about the principle of the vm snapshot based on qemu-dm, so the following below maybe a joke. Sorry for that... register_savevm() included in ioemu-qemu-xen/hw/*.c covers various kinds of hardware in order to save the state of current running vm. In this way, the file saved by the cmd of 'xm save domain snap...

Hello! I am doing Principle Componenets Analysis using "psych" package: mypc<-principal(mydata,5,scores=TRUE) However, I was asked to run a case-weighted PCA - using an individual weight for each case. I could use "corr" from "boot" package to calculate the case-weighed intercorrelation mat...

...f introducing a few false negatives). The overarching goal is to ensure that code behaves identically regardless of the order in which packages are attached. - A number of packages provide a function that appears to conflict with a function in a base package, but they follow the superset principle (i.e. they only extend the API, as explained to me by Herv? Pages). conflicted assumes that packages adhere to the superset principle, which appears to be true in most of the cases that I?ve seen. For example, the lubridate package provides `as.difftime()` and `date()` which ex...

Hello everybody, I am afraid this might be a stupid question, but after scanning a little bit through the help archive and the internet, I didn't come up with an answer myself. I have done a principle component analysis on a data set, which yields the mean response of 14 olfactory neurons to 16 different odors. When plotting the result in a biplot, it nicely shows me the odors in different positions in the principle component space. Additionally, the neurons are shown as vectors within this...

Would you please hepl me and explain how to read the PCA map (both of rotated and unrotated) in a concrete example. 2) Where I can find document relate: Plan S(A), S(A*B), S(A)*B?

When pass :cache param to ActionDispatch::Session::MemCacheStore, it should be removed from options, otherwise it remains "published". This violates the OOP encapsulation principle.

Hello, I have a problem with selecting the right type of sums of squares for an ANCOVA for my specific experimental data and hypotheses. I do have a basic understanding of the differences between Type-I, II, and III SSs, have read about the principle of marginality, and read Venable's "Exegeses on Linear Models" (http://www.stats.ox.ac.uk/pub/MASS3/Exegeses.pdf). I am pretty new to R and a search of the R-help archive did not answer my question (although I found some good pointers). In brief, leaving my covariates aside, I hypo...

That way I could write: 2) record.status_code = ''sent''; I am not sure which is better way to do this, especially according to DRY principle of Rails; in first case it seems that I have one more SQL statement in for every record processed. Second way does not seems preferred in Rails (or I just didn''t see it anywhere?) Does anyone have any suggestion about these? Thanks in advance, Bojan -- Bojan Mihelac Informatika Mihel...

...8, does not have any info in general, but a collaborator is saying that he needs the bbb8888 for documentation in the UUU object. A solution is to rerun the analysis, but the list is very long, the analysis will take 1 day. Is there any ready function that can modify an object? Or at least shows principles how to modify an object? I have labeled elements of U2 as (e) which needs an NA in the second position; (d) needs a name bbb8888 as a second column and as a second row and correspondingly in its rows and columns use value 1.0; NO change for (c); adding 0.0 in the second position for (b); and NO...
