Dear R user, I am trying to reproduce the results in Montgomery D.C (2001, chap 13, example 13-1). Briefly, there are three suppliers, four batches nested within suppliers and three determinations of purity (response variable) on each batch. It is a two stage nested design, where suppliers are fixed and batches are random. y_ijk=mu+tau_i+beta_j(nested in tau_i)+epsilon_ijk Here are the

Dear R gurus, I am trying to work out the problem given in Nested design - Montgomery - Design of Experiments p.561 I have attached a pdf of the data as well the anova table. It is a mixed model with Supplier as fixed effect and batches within the supplier as random effects. I am able to work out the error stratums as below using aov. Which agrees perfectly with the book example

Hi, I'm writing an AGI script to manage outgoing calls. We need to interrogate a database to work out which line a particular user is allowed to use for outgoing calls. However, I cannot find a way for my AGI script to access the SIP username. Does anyone know if this is possible (even if it is just passing a variable from extensions.conf to the script)? Thanks in advance, David

I appreciate the well-thought-out comments. To your first point, I am not sure what "glattering" means precisely (a Google search revealed nothing useful), but I assume it means something to the effect of overfilling the main namespace with too many names. Per Norm Matloff's counterpoint in The Art of R Programming regarding this issue, this is mostly avoided by well-defined,

One of the first things we had to implement in order to make LLVM usable is something very similar to what Justin has proposed. Centralizing control of the output in outs()/errs() would

I'm not going to argue at length about it, but it is worth thinking about. The only practical downsides of void are when newcomers take C's syntax for functions with no arguments a little

I have another round of questions about IR select canonicalizations. For the purity of this quiz, please disregard prior knowledge of how this is handled by instcombine or how this is lowered by your favorite target...of course we'll fix it. :) Some answers in the links below if you do want to know. Which, if any, of these is canonical? 1. Is a zext simpler than a select? a. define i32

The point is, that there are several possible problems. But. One the one hand they are not really problematic in my opinion (I do not care if my function has potential access to objects outside of its environment because this access is read-only at worst and it's not common practice to use this potential anyways). On the other hand I am not sure what the main()-idiom would actually add to

Tf-idf is most used used weighting scheme is easy to understand and has been used in other frameworks like lucene and many other places. okapi bm25(implemented in xapian) is theoretically better/improved measure than tf-idf and i am looking into various other weighting scheme which are there in xapian or can be implemented like TF-ICF(term frequecy inverse corpus frequency),TF-RF(term

I am not in favor of the change, which is a choice of rigor over usability. When I am developing code or functions I agree with this, and I view any warnings from R CMD check about shortened arguments as positive feedback. But 90% of my usage of R is day to day data analysis, interactive, at the keyboard. A lot of data sets that come to me have long variable names. What this change will mean

Hi, I think we are overloading the Layout references for garbage collection. If you are creating a reference (kindLayoutAfter) from A to B, that may not mean that you cannot garbage collect B for the end user. My thought on Layout references was that it only guarantees that atoms appear in Layout reference order. Why are we overloading this for Garbage collection (aside from saving space/code)

I just noticed that two key pieces of information are not given by the summary() command: N and SD. we are given the N missing, but not the converse. I know these summary value can be obtained easy, but can't understand why these two pieces of information are not provided with the other info. Thanks, Gerard

Hello all, I am willing to do "eliminating the void type" project. Is there anyone working on it? === Overview === The general concept is to replaced void with {}. And 'ret void' is a synonym of 'ret {} {}.' === Further Implementation Details === 1. Deleting VoidTyID 2. Deleting LLVMVoidTypeKind (one-to-one relation between VoidTyID and LLVMVoidTypeKind) 3. Use

Hi Suman, I think you can ascertain pureness automatically leveraging the compiler instead of manually tagging attribute to each method and call-site. It would seem like impurity should be a transitive attribute. So this would conflict with below. __attribute__((annotate("pure"))) int add(uint32_t a, uint32_t b) { // impure by calling printf... ... printf("%d + %d =

All, My apologies if this is a little long-winded and stream of consciousness-y :). SUMMARY: Why do we extend ActiveRecord instead of mixing it in to our model classes? Been thinking about my app''s models and starting to want to build something of a hierarchy. I have some commonality across 3 of my model classes and I''d liek to aggregate the behavior in a superclass.

Hi, FreeBSD libc Berkeley DB can leak sensitive information to database files. The problem is that it writes uninitialized memory obtained from malloc(3) to database files. You can use this simple test program to reproduce the behavior: http://www.saunalahti.fi/~jh3/dbtest.c Run the program and see the resulting test.db file which will contain a sequence of 0xa5 bytes directly from malloc(3).
