(PR#14226) -- Re: libgfortran misplaced in Mac OS X R install (PR#14226)
I am the guy who compiles the OpenMx binaries. We would be delighted
to place our package on CRAN, once the project is stable enough so
that we are comfortable releasing it to the larger public. Let's try
to track down where I made a mistake. Our Makevars.in file contains
the line:
PKG_LIBS=$(FLIBS) $(BLAS_LIBS) $(LAPACK_LIBS)...

BLAS benchmarks on R 2.12.0
Hi,
I saw on the mailing list and in the NEWS file that some unsafe math
transformations were disabled for the reference BLAS implementation
that is used in R. We have a set of performance tests for the OpenMx
library, and some of the tests have a x3-10 slowdown in R 2.12.0
versus 2.11.1. When I copy the shared library libRblas.0.dylib from
the 2.11.1 installation into the 2.12.0 installation, the slowdown
goes away. It seems reasonable that BLAS should conform to IEEE
requirements. For the purposes o...

FIML with missing data in sem package
Is there a way to use full information maximum likelihood (FIML) to
estimate missing data in the sem package? For example, suppose I have a
dataset with complete information on X1-X3, but missing data (MAR) on X4.
Is there a way to use FIML in this case? I know lavaan and openmx allow you
to do it, but I couldn't find anything in the documentation for the sem
package. Thanks!

easy way to fit saturated model in sem package?
...ll information maximum
likelihood). Here is exemplary missing data:
dat <- as.matrix(mtcars[, c("mpg", "hp", "wt")])
dat[sample(length(dat), length(dat) * .25)] <- NA
dat <- as.data.frame(dat)
It is not too difficult to write a wrapper that does this in the
OpenMx package because you can easily define paths using vectors and
get all pairwise combinations using:
combn(c("mpg", "hp", "wt"), 2)
but I would prefer to use the sem package, because OpenMx does not
work on 64 bit versions of R for Windows x64 and is not available from...

Profiling function that contains both C++ and Fortran Code
Hello,
I am trying to profile a function of OpenMx
(http://openmx.psyc.virginia.edu) for CPU time. My operating system is
OS X 10.10. OpenMx contains C++ and Fortran code. I have read the
section regarding profiling compiled code in the manual
(https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Profiling-compiled-code).

FIML in R
Does anyone know if someone is developing full-information maximum likelihood (FIML) estimation algorithms for basic regression functions, like glm()? I think that having FIML options for workhorse functions that typically use ML would give R an edge over other statistical software, given how well FIML performs in missing data situations compared to ML.
While my current level of programming

Two R editiosn in Unix cluster systems
Dear R Devel
Some of our R users are still insisting we run R-2.15.3 because of
difficulties with a package called OpenMX. It can't cooperate with new R,
oh well.
Other users need to run R-3.0.1. I'm looking for the most direct route to
install both, and allow users to choose at runtime.
In the cluster, things run faster if I install RPMs to each node, rather
than putting R itself on the NFS share (but I co...

structural equation modeling
Dear R-help,
I am interested in using structural equation modeling.
Just getting started with it, but I'm looking for suggestions for packages.
As an aside, what's the best way for looking for packages at CRAN?

multivariate modeling codes
HI,
I am relatively new to R and would appreciate some help or directions for
this.
I am trying to model 3 longitudinal outcomes jointly and to identify some
predictors for these 3 joint outcomes (all continuous). I am trying to find
some codes that I may modify to do this but cannot seem to find anything.

SEM validation: Cross-Validation vs. Bootstrapping
...that the approach I've suggested is the way to go? Are there others besides Dr. Harrell that I could cite in pursuing this approach?
2. Does anyone know of some substantial published applications of this approach using SEM?
3. Would any of the available R packages for SEM (e.g., lavaan, sem, OpenMx) be particulary straightforward to use in doing the bootstrapping? Thus far, the SEM has been done using MPLUS. I've not tried SEM in R yet, but would be interested in giving it a shot.?The SEM itself is relatively straightforward. Four latent variables, one with 7 indicators and the others wit...

Cluster: Various GCC, how important is consistency?
...sted I try to build with the GCC that is provided
with the nodes, which is gcc-4.4.7. To my surprise, R-3.3.1 compiled
with that. After that, I got quite far, many 100s of packages
compiled, but then I hit a snag that RccArmadillo explicitly refuses
to build with anything older than gcc-4.6. The OpenMx package and
emplik packages also refuse to compile with old gcc
The cluster uses a module system, it is easy enough to swap in various
gcc versions to see what compiles.
I did succeed compiling RcppArmadillo with gcc 4.9.2. But Rcpp is not
picky, it compiled with gcc-4.4.7.
I worry...

Factor analysis and cfa with asymptotically distributed data
I have friendship data which is strong skewed. So it doesn't make sense to
use maximum likelihood methods for fa and cfa.
But I couldn't find any function for asymptotically distributed data for doing a factor analysis. Only: apca() but there is no possibility to allow for factor correlations.
The same problem is with sem() I couldn't get any solutions for my model because of the
