Can you explain your definition of structured/unstructured loops/regions. A structured loop does have just one exit? Does a unstructured region have multiple exits, or it just contains unstructured code? Tobi

error message from gls(), unstructured in lower triangle, identical diagonal, help.
Hi, nlme users, I am fitting a model for repeated measures, using gls(). The var-cov structure is UNSTRUCTURED in lower triangle and identical for the diagonal, for which I still have no idea how to fit using PROC MIXED. The error message is as follows: Error in "coef<-.corNatural"(*tmp*, value = log((cStNatPar + 1)/(1 - cStNatPar))) : NA/NaN/Inf in foreign function call (arg 1) I h...

(UN)structured E1
Hi all. We are getting our first PRI line to use with Asterisk and one of the technical specifications is about framing, structured or unstructured. The main difference about them is almost clear for me: http://ckp.made-it.com/g704.html says: "G.704 is the framing specification for G.703. A carrier can 'steal' a 64kbps time slot (TS0) from a 2.048 Mbps line and use this to provide timing. The result is that 31 time slots are...

[RFC] A New Divergence Analysis for LLVM
...ngs that are resolved by the new analysis. - Why the current DivergenceAnalysis is broken - LLVM already includes a DivergenceAnalysis for GPU kernels. It is used in the GPU backends and to re-structure CFGs (StructurizeCFG pass). However, the existing DivergenceAnalysis of LLVM is broken for unstructured CFGs (bug report [9]): Example B: undetected divergence in unstructured control. entry:  divergent branch to B and C B:  uniform branch to C and D C:  %phi.var.hidden = phi .. <- undetected DIVERGENT phi  br D D:  %phi.var = phi .. <- detected DIVERGENT phi in IPostDom of entry  Ret...

Generalised Estimating Equations on approx normal outcome with limited range
...ther the measures are related to certain covariates, and I have tried the generalised estimating equation function geeglm (library geepack) with the 'gaussian' family details like so: geeout <- geeglm(outcome ~ covariate1 + covariate2, id=familyID, family=gaussian, data=dat, corstr="unstructured") But I'm thinking that the limited range of the outcome violates the assumption of normality and that the results could be off. Q: Is there a way in R, either in geeglm or another appropriate function, to take the limited range of the outcome into account? Another aim of the analysis i...

R with CouchDB?
Hello all, I'm kind of surprised that searching the archives and Googling haven't given me a result for this... I've got a large amount of data that is a good fit for CouchDB; it's reasonably unstructured, and such structure that exists is quite fluid. I want to slice the data in many different ways, some of which really don't fit well with a relational database model. I could probably do it using a relational DB, but it just doesn't feel like a good fit. What's the best way to go abo...

Developmental version of Matrix package for R-1.9.0

I would be happy to correspond off-list if you would like a preview of the capabilities. Metis is a package for partioning unstructured graphs, partitioning meshes, and computing fill-reducing orderings of sparse matrices. Although the entire source code for Metis is included in the Matrix package I am only using one of the functions for computing fill-reducing orderings. Perhaps those who are working on graphical models may want...

GLM, LMER, GEE interpretation
...t I am observing differences between the three. The first model is a quasibinomial without any subject effects using glm. The second is a random-effects model using lmer. The third model is a generalized estimating equation using gee from the gee package in which I cluster for the subject using an unstructured correlation matrix. The results of the first and the third model almost coincide, but the second, using lmer, shows an insginficant coefficient where I would expect a significant one. The other 2 models show the coefficient significant. I do not really have experience with gee. Therefore I apologi...
