search for: modelised

Hello, I am working on the backend for an architecture which has a compare instruction that affects only an internal condition code register (basically a sub without destination register). I get the following assert in the scheduling phase: llvm::SDNode::getValueType(unsigned int) const: Assertion `ResNo < NumValues && "Illegal result number!"' failed. It turns out

Hello, I am beginning with R and I would like to test a non linear model. But I do not find exactly wath I am looking for in nls packages (or I do not know where to search). I would like to try a model like this : y=b * x exp(n)/(a exp(n) + x exp (n)) Where a = a0 + a1z b= b0 + b1z x and z are variables y the variable that I am trying to modelise a0, a1, b0 and b1 are parameters to determine. I

Hi, The function help.start() assume that the brower is netscape which is no longer the dominant brower in used. I am using now opera and other use mozilla or Microsoft IE. I can always type help.start(browser="opera"), but it is not convenience: I would like to be able to set the default brwsernone for all. But the real bug is that even after launching

I know it is possible to use the character "#" to comment lines in script files. Is it possible to give an argument (just like skip) to the fuction read.table to avoid reading commented lines in data files. I want to use this function to read a table in a data file like this #------------------------------- x y z #my data begin here 1 2 3 12 3 4 1 0 1 # no comment !!! 2 3 5

You want to model the condition codes as a pseudo-register rather than using OutFlag. See the X86 back end. > I get the

I would like to import "tif" images in R and I do not find any function that can do that. In Matlab there exists the function "imread" that can read the most known images format. Does a similar function exist for R ? Thanks in advance -- Herve CARDOT ____________________________________________________________ Unite Biometrie et Intelligence Artificielle, INRA Toulouse BP

Dear all, I have a serious problem to solve my model. I study over exploitation of fish in the bay of biscay (france). I know only the level of catch and the fishing effort (see data below) by year. My model is composed by the following equations: * the growth function Gt(St) = r*St*(1-St/sbar) with Gt the growth of each period t r intrinsec growth of the stock sbar carriyng capacity of the

Dear R-users, I have written the following code to generate some trellis plots. It works perfectly fine except that it is quite slow when it is apply to my typical datasets (over several thousands of lines). I believe the problem comes from the loops I am using to subset my data.frame. I read in the archives that the tapply function is often more efficient than a loop in R. Unfortunately ,

Hello, I have improved a little the NHW codec.I have improved the dequantization in the wavelet HH band, and little improved the -l2 (and lower) quality setting.I have also added a -l3 lower quality setting (-15Ko, exp), I have increased the quantization for this other setting, and I start to remove higher wavelet coefficients, but this is not optimal... The artifacts start to be noticeable for

.... It is quite efficient (compared to other classical methods) for reducing the size of histograms (my first intent) but also DCT, FFT, Huffman tables ... It is a low complexity (add/sub, shift, masks ...) code that works well on small datasets that have some kind of correllation that is not easily modelised. Depending on the type of data (large variance and grouped chunks), it can be used to compress/pack as little as 4 or 8 values, sometimes beating Rice and Huffman codes. It requires O(N) temporary storage for compression (usually N plus a stack in log2(N)), and it can be modified for in-place deco...

Dear, At the request of a number of potential contributors, we have decided to extend the deadline for receipt of papers to be presented to The 6th International Conference: Sciences of Electronics, Technologies of Information and Telecommunications SETIT 2011. This deadline is extended to December 31, 2010. This conference will be held in Tunisia, 23-26 March 2011. The paper submission is

Invitation Dear We would like to invite you to join us for the 5th International Conference named Sciences of Electronics, Technologies of Information and Telecommunications SETIT 2009 which will be held in Hammamet-Tunisia from 22 to 26 March 2009. As you know, this International Conference is under the supervision of Professor Lazhar BOUOUNI, the Tunisian Minister of Higher Education and

Hello everyone, I am searching for a covariate selection procedure in a cox model formulated as a counting process. I use intervals, my formula looks like coxph(Surv(start,stop,status)~ x1+x2+...+cluster(id),robust=T) where id is a country code (I study occurence of civil wars from 1962 to 1997). I'd like something not based on p-values, since they have several flaws for this purpose. I turned
