Hi guys Recently a wanted to look at the opotunities which are suported by the labrary of tcltk. Unfortunatly I couldn't load the library and it occured the following error message: Error in firstlib(which.lib.loc, package) : TCL_LIBRARY is not set Error in library(pkg, character.only = TRUE) : .First.lib failed I've tried to load it in sveral ways. I reinstalt the

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

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

Hi All, I've developed a pass to render machine functions as HTML pages with some accompanying information about liveness and register pressure. Current features: Renders machine functions, optionally displaying estimated register pressure for selected register classes, and liveness for selected intervals. The following command line options can be used to enable and customise the

Dear all Currently, I'm implementing the generalized hyperbolic distribution into Splus. Unfortunately the Bessel function is not implemented in Splus. In R the Bessel function does exist but it is an internal function and I'm not able to look at the code. Is there any possibility to see the code of the Bessel function in R or does anybody has an implementation of the Bessel function in

Hi, I'm having trouble with auth_password() failing on my linux box using yellow pages. I've tracked the problem down to the following: pw_password = "RMf.YivanoZc2,o01N" encrypted_password = "RMf.YivanoZc2" This fails on the return(strcmp(encrypted_password, pw_password) == 0). because crypt() only returns 13 characters. I seem to remember the

the new src/lib/ipwd.c introduced in 2.0.12 no longer compiles on solaris. Under solaris, the *_r routines doesn't pass in result as the last parameter and return errno - it just returns result. obviously a job for configure..... -- Roger Fujii<rmf at lookhere.com>

[Please use the subject line!] In the help page for summary.lm, the "Value" section says that the returned object has a component called "fstatistic", which has the F-statistic and the associated numerator and denominator degrees of freedom. You can get the p-value by something like: fstat <- summary(speciallinearmodel)$fstatistic pval <- pf(fstat[1], fstat[2],

Hi everyone, I've just notice a problem with ordered factor variables. It appears that row-binding two ordered factors together looses the ordered attribute. The following example happens both in R1.3.1 and R1.4.1 (on RedHat 7.2): > y <- ordered(gl(3,6),labels=1:3) > y [1] 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 Levels: 1 < 2 < 3 > data <-

Hello - I need to read in some tables that are embedded within data files like this: line 1 line 2 data table 01000 10110 00011 end table line 3 line 4 Is there any way to read just the data by telling an input device to start reading when it encounters the keyword "data table" and stop reading at "end table"?

Actually 0904.huawei.com is just one of my test domain. I also built domain naned vds.huawei.com. Same problem exsts. Besides, samba 4.5.16 doesn't have this issue.

Sorry, maybe it's easy but I haven't found anything useful: how can I obtain a list C that contains all the members in the list B that are not in list A? This are lists of nanes, not numbers!
