Hello, I am trying to convince our IT Manager that R is as safe as possible from IT security point of view - could you point me to something on the web / some reasons for why this is true? I do not think he has a specific concern but does not know the software and would like to understand the security implications. Thanks in advance Best Regards Martin Hanek Actuarial Analyst Glacier

Have you tried web searching on " R constrained linear regression" or similar. There seemed to be resources related to your issues when I looked. You might also search on rseek.org . There are apparently several packages that do regression with constraints, but I don't know if they fit your situation. Cheers, Bert Bert Gunter "The trouble with having an open mind is that

The nls2 package can be used to get starting values.

Ok, and if I would just like to force my slope coefficients to be inside an interval, let's say, between 0 and 1? Is there a way in R to formulate such a constraint regression?

This is a quadratic programming problem that you can solve using either a quadratic programming solver with constraints or a general nonlinear solver with constraints. See https://cran.r-project.org/web/views/Optimization.html for more info on what is available. Here is an example using a nonlinear least squares solver and non-negative bound constraints. The constraint that the coefficients sum

Hi Gabor, Thanks a lot for your help! I tried to implement your nonlinear least squares solver on my data set. I was just wondering about the argument start. If I would like to force all my coefficients to be inside an interval, let?s say, between 0 and 1, what kind of starting values are normally recommended for the start argument (e.g. Using a 4 factor model with b1, b2, b3 and b4, I tried

If the slope coefficients sum to a constant, the regressors are dependent and so a unique solution is impossible (an infinity of solutions would result). So I think you have something going on that you don't understand and should consult a local statistician to help you formulate your problem appropriately. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people

Hi all, I hope you are doing well? I?m currently using the lm() function from the package stats to fit linear multifactor regressions. Unfortunately, I didn?t yet find a way to fit linear multifactor regressions with constraint coefficients? I would like the slope coefficients to be all inside an interval, let?s say, between 0 and 1. Further, if possible, the slope coefficients should add up to

Hello everybody I need some help. Currently, I'm translating a code from Splus to R. In Splus code there is the function nlminb (Nonlinear Minimization subject to Box Constraints) used. Does anybody know an equivalent function in R? Thanks for help Kind regards, Beat Huggler _____________________________________________ Beat Huggler Quantitative Analysis RMF Investment Management

Hello, I'm willing to implement call barring for incoming and outgoing calls and I would like to discuss it with the list first, since I think It can't be implemented in a 'natural way' and I will need to use agi scripting - database. Process would be: 1. incoming calls priority 1, call incoming.agi, select all the blocked cli's for the called user, if caller is on

Hi, On asterisk 1.4.4 I have an strange effect on agents answering queue calls: If an agent does set current call on hold the phone immediately gets connected to the next incoming call. What might cause this effect? How can it be removed? Elmar

Hi, I intend to let several SIP-phones on my asterisk ring cascaded on incoming calls. First only phone 1 should ring, after 5 seconds phone 2 should ring in addition and after additional 5 Seconds phone 3 should also ring. How can I realize that correctly? Currently I do use Dial(SIP/1,5) Dial(SIP/1&SIP/2,5) Dial(SIP&1&SIP/2&SIP/3) But this seems not to work correctly on

Hi, my Vista box does hang if I try to copy an File on an Samba share. - Hanging does happen on both, explorer and CMD. In Explorer it shows up to calculate how long it might take. In CMD nothing happend. - Afterwards Vista refuses to shut down. - Creating an File on the Share and saving it from within notepad does not cause any trouble. - Limiting protocol to lanman2 seems to help

I have a big performance Problem when using Pegasus Mail storing it's Mail on on an samba Share. I assume PMail does write small blocks of data when saving files. The same performance degeneration is seen when copying files with "type file >copy" instead of using the copy Command. Client OS is Windows-Vista, Server is Samba Samba 3.3.4 Any Hints to optimize samba here? Elmar
