Is there a function in R for constrained linear least squares? I used the matlab function LSQLIN: my aim is to obtain non-negative regression coefficients which sum 1.

Dear Colleagues, I hope to know how ordinal logistic regression with a mixed model is made in R. We (My colleague and I) are studying the behavior of a beetle. The attraction of beetles to a stimulus are recorded: the response is Slow, Mid, or Fast. They are based on the time after the presentation of the stimulus to the beetles. Because we do not observe the behavior continuously but do

Hello everyone, I want to calculate type I error rate for modified F statistic for one way robust anova. I need to find the j group trimmed mean and winsorized sum of squared deviations. Here I attached my code for j=2 to make it simple. Originally I have j=4. Hope you can help. I need to run it for 1000 times My problem is: i) the value of F-test obtain from my simulation below is in negative

Dear List, I'm new in R. I'm trying to solve a simple constrained optimization problem. Essentially, let's say I have a matrix as in the object 'mm' inside the function below. My objective function should have a matrix of parameters, one parameter for each element 'mm' (4 in this case). The problem is to select the value of the parameters to maximize the function

Hello, i would like to import this txt file: Giorno;PM10 2006-01-01 10:10;10.3 2006-02-02 20:22;50.3 2006-03-03 23:33;20.1 .........

Dear HelpeRs, I am trying to use an thirdy-part library under Linux (the library is developed both for Windows and for Linux). I have tried different solutions (with the library developer) but we are not able to solve the problem. So I try to ask for your help in order to escape from the full stop where we are at the moment. The problem looks to depend on the dyn.load function (technical

Dear List, I'm trying to solve this simple optimization problem in R. The parameters are the exponents to the matrix mm. The constraints specify that each row of the parameter matrix should sum to 1 and their product to 0. I don't understand why the constraints are not satisfied at the solution. I must be misinterpreting how to specify the constrains somehow. library(alabama) ff <-

Dear all, I am trying to do weighted regression using lm function in R. However, I have a question why the results from 1) lm(formula = Y~aX, weight = w) 2) lm(formula = wY~waX) are different. Aren't they supposed to have the exactly same result? Below are the R code to see difference in regression results MatY <- c(0.15,0.42,0.31,0.22) MatX <-

Hi R People: If you have a linear programming problem in which some of the constraints have the "<=", some have ">=" and some have "=", all in the same problem, should the solver work? I'm having trouble with that. Any help much appreciated! Sincerely, Erin Hodgess mailto: hodgess at gator.uhd.eud whoops! mailto: hodgess at gator.uhd.edu

This morning I received this report of a change to the SELinux context of /etc/posfix/main.cf on one of our hosts. from: system_u:object_r:postfix_etc_t:s0 to: unconfined_u:object_r:postfix_etc_t:s0 The contents of the file have been verified as unchanged. There was a yum update applied yesterday to this host and this may be an intended alteration. However, can anyone confirm this for me?

Hi , I am struggling with these two question . Any help would be appreciated ,Im looking at doing them on r ? 1.

We have a bunch of lists hosted on a CentOS-4.9 server running sendmail and mailman that we are moving to a CentOS-6 vm running postfix and mailman. I am testing the setup and I am running into a problem no doubt caused by my own ignorance wrt postfix. Based on groking the web I discovered that the recommended way to configure postfix to work with mailman is a script called

Hi, thanks for your answer. I confirm, mitigate this issue is very very easy. There are other issues with high severity for example CVE-2019-17558. Description: Apache Solr 5.0.0 to Apache Solr 8.3.1 are vulnerable to a Remote Code Execution through the VelocityResponseWriter I think for this issue there is only a solution, upgrade Solr to 8.4. It's Correct? So, with Dovecot is it possible

I am runnig posfix on Centos 4.4 as a Mailgateway. It only accepts mails for domains and then forwards mails to Lotus domino Server. All clients sends outgoing mails to that Lotus domino Server. Then , That Lotus Domino Server sends mails to Postfix mailgateway. This postfix mailgateway sends mails to all the destinations. But, This Postfix mailgateway has about 150 messages in the mailq.
