problems with for loop
Hello,
With this program I try to repeat analysis for different years. The
results of the analysis are not printed when in the loop, except for the
year sequence. What is wrong?
Thanks a lot.

Problem with predict() and factors
I am working on a script that takes numeric performance indicators and runs
them against a series of regressors (dummy regressors, yes\no stuff via 0
and 1, e.g. Was is Christmas this week 0=no, 1=yes).
The script is as follows (Written as a function):

normalised Voigt random numbers
Dear list,
I would like to generate random numbers from a Voigt distribution,
hopefully in a way as simple as getting random numbers from a normal
distribution with 'rnorm'. Is there any package to do this? Speed is an
issue in this application. Or, as the Voigt distribution is a
convolution of a Gaussian and a Lorentzian, can I simply combine random
numbers from rnorm and rcauchy in some

first value from nlm (non-finite value supplied by nlm)
Dear expeRts,
first of all I'd like to thank you for the
quick help on my last which() problem.
Here is another one I could not tackle:
I have data on an absorption measurement which I want to fit
with an voigt profile:
fn.1 <- function(p){
for (i1 in ilong){
ff <- f[i1]
ex[i1] <- exp(S*n*L*voigt(u,v,ff,p[1],p[2],p[3])[[1]])
}
sum((t-ex)^2)
}

Getting Sphericity Tests for Within Subject Repeated Measure Anova (using "car" package)

I am trying to do within subjects repeated measures anova followed by the

Pseudo-Voigt fit
Hi, I am sorry for this question, but I am trying to speed up an
application....
I will need to fit many x-y data sets (input from text files) to
4-parameter Pseudo-Voigt peak function.
Until now I used SigmaPlot macro to do it (enclosed just in case...)
peaksign(q) = if(total(q)>q[1], 1, -1)
xatymin(q,r) = xatymax(q,max(r)-r)
[Parameters]
a = if(peaksign(y)>0, max(y), min(y))

Test for Homoscedesticity in R Without BP Test
Hi Deepak,
In econometrics there is another test very often used : the white test.
The white test is based on the comparison of the estimated variances of residuals when the model is estimated by OLS under the assumption of homoscedasticity and when the model is estimated by OLS under the assumption of heteroscedastic.

Puppet code review - suggestions and options
We are looking to implement a code review system that will require a review
of the code before it gets to production servers. I have been looking into
many different options, and would love some feedback and experiences from
other users.
Our puppet is in a git repo. We have 3 primary environments with a branch
of puppet for each of them. All of our puppet info is in the git repo
