Rational functions (ratios of polynomials) often provide good approximations to many functions. Does anyone know of any literature on nonlinear modeling with rational functions, sequential estimation, diagnostics, etc.? I know I can do it with "nls" and other nonlinear regression functions...

Gerald, No worries. This patch is required if your using Rational ClearCase and you don't want everyone to have access to it. It's to fix a brokenness (IMO) within ClearCase, and maybe other programs. Our windows primary group has 10k+ users... I will shoot it off to Rational, so they can provide it to there customers. I was hoping it could be applie...

Are there implementations of, e.g. Neville's algorithm, for interpolating polynomials through some data points? Nevilles' is an improvement on Lagrange interpolation. And how about interpolating rational functions? I could not find anything at rseek.org or at crantastic.org. thanks -- View this message in context: http://r.789695.n4.nabble.com/functions-for-polynomial-and-rational-interplation-tp3595334p3595334.html Sent from the R help mailing list archive at Nabble.com.

...y, who was one of the leading mathematical political scientists in the US (before his untimely death). It has been continued by his students, primarily Ted Turocy. In Gambit, great care is taken to avoid any floating point calculations involving fractions until the latest possible step. There is a rational number class and fractions are added and subtracted in a more exact way. I think it "lowest common denominator" or similar concept. (I remember that detail mainly because the switch from 32 bit to 64 bit integers caused memory allocation troubles). (Come to think of it, I believe the...

Hi - I'm getting timouts trying to access us1.samba.org or I'd look through the archives first. Anyone currently supporting any versions of Rational's ClearCase/samba/UNIX/NT? We are currently running samba v2.0.3 on both HP-UX 11.0 (vob server) and Solaris 2.5.1 (view server). Rational ClearCase v3.2.1 on the two UNIX and NT Workstation 4 (some SP3, some SP4) We currently support UNIX/NT interopration via both Hummingbird's and Ne...

In the R source, nmath/pnorm.c contains the code for a rational function approximation for the normal cdf. These constants are listed: const double a[5] = { 2.2352520354606839287, 161.02823106855587881, 1067.6894854603709582, 18154.981253343561249, 0.065682337918207449113 }; The source file cites a paper by...

Is there anyone out there successfully using Rational Clearcase with SAMBA? Was there any special changes you had to make to get it to work? We were told by Rational specifically not to use SAMBA and wanted to get the other side.

Hello Samba, We tried to use samba-2.2.4-1 with Rational ClearCase and had a problem using WinBind. ClearCase requires the primary group id to be set to the clearcase users group. WinBind sets the primary group to something like DOMAIN_GROUP_RID_USERS. I am including the patch we made to samba-2.2.4 to get things working. I have added two new smb.c...

Andrew, Thank you for your suggestions. The real problem is Rational Technical support. When you pay someone 100k+ they tend to look for any excuse to deem you "unsupported". If you don't have your default group set to the clearcase user group, then technical support will decide that thats where your problem is! I am sure you know how that goe...

HI all, So I'd like to log the user's operations on some shares. As I need to know who made what when. I'd read a previous answer from Andrew about auditing, so I can see loggued operations.

The results are at www.rational.co.za/speex.csv Each of the 11 quality settings is tested 3 times (narrow, wide and ultra wide band). Strangely narrow band quality 11 outperforms all wide band tests, but it can be due to my subsampling or some other inaudible effect like delaying. You can import it into Excel and sort it...

This falls under the 'getting clearcase to work with samba' category. Does anybody know if the clearcase albd server actually uses samba to access files (or anything else) on the unix side? I am having 'discussions' with rational (the clearcase people). The nt user running clearcase to access some unix-side views connects to the unix side using a set of credentials that have access to the user's unix-side files. In addition to the clearcase user, there is also the clearcase 'albd' service that spawns off a n...

Hi There, Users in some european countries like to write 1.234,56 instead of 1,234.56 What would be the easiest way of accepting this number format? For output, I''m using a formatting helper, but I haven''t figured out how to do it for input. thanks, js
