non-linear contrained optimization
All,
I have searched the previous help boards and discovered the problem
with Rdonlp2 - Specifically, its non-availability. I thought that this
was my solution, but perhaps there is a better way that you all could
help me with. I imagine that this problem is trivial to people such
as the experts on this mailing list.
I am trying to solve this problem over and over again in a simulation:

activerecord problem with contrains,belongs_to and has_many keyword
Hi,
I have two models:
AdvertisementImages (table: advertisement_images)
Advertisement (table: advertisements)
The table advertisement_images has a foreign key to advertisements
called advertisement_id. Both tables has one entry where the entry in
dvertisement_images belongs to advertisement.
The model code looks lik this so far:
class AdvertisementImages < ActiveRecord::Base

Why the contrain does not work for selecting a particular range of data?
Dear:
Continuing the issue of 'ifelse'! I selecting the data whose 'x2'=1 for maximizing likelihood. I used two way to do this but the results are different.
1.Way one I use the data for x2=1 and run the program. It works for me. Tthe program is described as below:
function (parameters,y1,x11)
{
p<-parameters[1]
alpha1<-parameters[2]
beta1<-parameters[3]

constrained optimization using nlm/optim?
I'm looking for an example of a simple R script that impliments a
contrained nonlinear function using nlm or optim. I'm not exactly sure how
to impliment the constraints within the objective function that is passed
to nlm/optim.
obj.func <- function( p ) {
x(p) <- unconstrained obj function value
if( constraint1 > something ) {
obj.func <- x(p)
} else {

(no subject)
Dear R users,
Please excuse my inexperience. I am trying to contrain the coefficients of
my linear regression to equal one when using the <-lm(...) command. I've
searched "help(glm)" "help(model.offset)" etc. but I am unable to figure out
where to put this constraint. Your help would be greatly apprciated.
Thanks.

It would be great to document the replacement. This is not a small

Has anyone seen this issue? We're running containers under CentOS 7.2
and some of these containers are reporting incorrect memory allocation
in /proc/meminfo. The output below comes from a system with 32G of
memory and 84GB of swap. The values reported are completely wrong.

ARM7 Speex decoder
Dear Jan
My intention is to read a piece at time of an .ogg file (stored in and external Multimedia card) decompress it and render it on and LPC2000 DAC. Because I don't have enough RAM memory to load the complete ogg file, I must read only a piece of file at certain time, then decompress and render it, and repeat the previous process until the end of the file. The problem is that I don't
