gday gurus, could someone please help me with this one? Can't find it in the doco. summary of my lm object gives "Pr(>|t|)" but coef doesn't. How do I get hold of these probabilities within an object? There doesn't seem to be an appropriate attribute within the object - I was hoping for something like "my.lm$probabilies". I was hoping to grab the best t scores at run-time. thanks, John Strumila -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-...

...calculate p-value to findout definitely expressed genes compare A to B situation. I got this data(this is a part of data) from whole organism , and each number means each expression values (that means, we could think 'a' gene is 13 in A situation, and it turns 30 in B situation) To findout probability, I'm going to use Audic - Claverie Method. ( The significance of digital gene expression profiles. 1997) But using this equation p(x|y), I have to calculate (x+y)! first. but I can't calculate (157+221)! or (666+1387)! in R. That's probabily the handling problem of huge number, Ho...

Hi there Yes, I know very little of ruby. I must take a crash course? Probabily. Anyway, I try to ask this here. I have a control: customer_controller. From here, I can do something like: @id = 1 @customer = Customer.find(id) Now @customer will contain all the fetched record for customer with id = 1. Great. From this controller I will render an html page. Somewhere the view will print test.

I'm running Samba 4.1.6 with Ubuntu 14.04.1 LTS Little Endian on a Power 8 box. As I said in a previous post, I can't mount any share from machine. I tried the same configuration with Samba 4.1.11 on Ubuntu 14.10 Little Endian on Power 8, and it works fine. I'm probabily wrong, but is there a bug in the binary distribution of Samba on Ubuntu 14.04.01 Little Endian, maybe

I have an action and I am testing it like this: The action: ========== def create @event = Evento.new(params[:event]) @event.aproved = false if @event.save redirect_to :action => "index" else render :action => "new" end end The RSpec test: ============== before do @event = mock_model(Event)

Dear R Developers: I have been playing with R, release 2.0.1 for a week now and have detected = that all stat functions related to distribution probabilities have the same= problem: 1.- The log.p parameter of all distribution functions, when set to TRUE, re= turns a extrange value. Accoding to the manual, when set to true, it should return log(p) probabili= ty. So to my understanding, setting to true this parameters is the same as = getting the L...

...ns the log odds can be computed.Is that right? My problem is this : in my data set , the IVs are continuous variables, do I still have to generate such a table and compute the log odds for each level of IV according to which the log odds are calculated? In R , fitted(fit) gives the fitted probability for DV to be 1. Dose the observed probability exist ? If it does exist , how can I extract it ? If the IV is cartegorical , the DV can readily changed to be a tow-culumned matrix, thus log(the observed probabily/(1-the observed probability) might be the "log odds". I wonder what if the...

hello, I am using the ROC package to evaluate predictive models I have successfully plot the ROC curve, however ?is there anyway to obtain the value of operating point=optimal threshold value (i.e. the nearest point of the curve to the top-left corner of the axes)? thank you very much, jose daniel anadon area de ecologia universidad miguel hernandez espa?a

Dear all, I am quite new with R and I have a problem with plotting a binomial regression line in a plot. This is what I type in: > model<-glm(Para~Size,binomial) > par(mfrow=c(1,1)) > xv<-seq(3.2,4.5,0.01) > yv<-predict(model,list(area=xv),type="response") > plot(Size,Para) > lines(xv,yv) The error message that I get is: > Error in xy.coords(x, y) :

Hello Again Rails Folk! I''m trying to creat a page similar to what the person is doing here... http://mudabone.com/aietc/?page_id=410 Instead of doing it the way he/she has, I decided to use RJS files, or at least I tried. Here''s my view <%= start_form_tag %> <%= javascript_include_tag "prototype" %> <p> Union: <div id="union">

Hi, anyone here is using HyperVM? As you probabily know, the owner of LxLabs has killed hitself (i want to make my condolences to his family): http://timesofindia.indiatimes.com/Bangalore/Techie-hangs-himself-in-HSR-Layout-/articleshow/4633101.cms HyperVM has some big vulnerabilities and we don''t know if they will be fixed. We don''t know if the licensing server will be kept

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to
