Hi, I am trying to do multiple regression on a set of data using backward stepwise regression....however backward stepwise regression is critised for overfitting data. To actually observe the bias and to come up with a better method to use..Could you all stats experts kindly give me pointers to any alternative procedure (or references) to use over backward stepwise regression from your

I'm fairly new to VoIP, and brand-new to Asterisk. I am wondering what are the best/least expensive phones or phone adapters to use with Asterisk, both wired and WiFi. I would appreciate any insight or recommendations you may have. Thanks, James arbaughj@myrealbox.com

Dear All, My question is more a statistical question than a R question. The reason I am posting here is that there are lots of excellent statistician on this list, who can always give me good advices. Per my understanding, the purpose of propensity score is to reduce the bias while estimating the treatment effect and its implementation is a 2-stage model. 1) First of all, if we assume that T =

ActiveRecords with composite primary keys now seem to happily support find/create/update/destroy options. Url: http://compositekeys.rubyforge.org Background: Rails/ActiveRecords has long been critised for not supporting legacy databases, especially composite primary keys. This gem extends ARs with this support. Cheers Nic -- Posted via http://www.ruby-forum.com/.

Hello, (first post) You probably don't want to hear about my Linux-related story, so I'll cut telling you that about 5 months ago I switched from XP to Ubuntu. I've been a C/C++ programmer since I was 13 (2 years go), so I consider myself to understand a great deal of things (but hey, what is my opinion worth nowadays?) Anyway, In this post I'd like to report my Successes and

This is a re-post as it was pointed out that I replied to a different thread instead of creating a new post. Sorry for the additional traffic. Mike Dear All, I understand the excitement surrounding a service like Asterisk, and how easy it is to jump in and ask a heap of questions. I also know how frustrating it can be dealing with a 200+ post per day mailing list as one of the question

...arranged that data in a data.frame called roiData I want a linear model of groupmembership, condition and roi to predict the mean signal value (as all the UV are kategorial and the AV is numeric this may be called ANOVA). As a first step I want to model all possible effects and their interactions (critisism that such a theory free hypothesis testing procedure is hardly resonable aside) I tried the following call (worked out with help of the following internet resources http://www.psych.northwestern.edu/Misc/s+.html example 5 ?Notes on the use of R for psychology experiments and questionnaires? b...

Hi there. I made a couple of noted regarding the speex API. These are not meant be seen as critisism - rather constructive suggestions.

I have started with using R on Windows, and I am really happy about the system. Now, one of my other ambitions is to learn how to use Linux, so yesterday I downloaded OpenSuse and installed that. The next problem was to try to use R with Linux. And there I met the wall. I've understood that RPM's are somewhat like installing programs on Windows, so that was downloaded and started

Dear all, I am trying to get an estimate of the intercept for a linear model. In this case, I know the slope of the model, can anyone tell me how to constrain the formula in lm() so that it only estimates the intercept not the slope?
