search for: contrain

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:

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 file_column

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]

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...

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. [[alternative HTML v...

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. # cat /proc/meminfo MemTotal: 9007199254740991 kB MemFree: 9007199224543267 kB MemAvailable: 12985680

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
