Hi, Our department has detected a bug in the implementation of the Kinderman-Ramage generator for normal random variates in version 1.7.0, which can be seen from the below R session. (Consecutive calls for chisq.test(...) always gives p-values very close to 0.) We have already encountered this bug in version 1.6.2 The error is in file R-1.7.0/src/nmath/snorm.c Here is a patch f...

...modify results used for comparisons in the tests. Since package testing is usually for code checking rather than statistical results, not using the best available generator is not usually an issue. Most of my own package testing already specifies the generator, lots uses "buggy Kinderman-Ramage" because tests were set up a long time ago. I will have to change package setRNG which warns when the default generator changes.

If this goes into base R, what's the best way to do it? What was the protocol for migrating away from the "buggy Kinderman-Ramage" generator, back in the day?

Today I struggled for hours to understand some unexpected package test results. It turned out that this is because package "parallel", buried deep in my dependencies, calls runif() during it's initialization and in this way changes the random number sequence. This seems to be a part of a more general question--which kind of functions can we trust if we want to preserve random

...etting old and forgetful I can remember exactly one such change where behaviour was changed, and (one of the) generators was altered---if memory serves in the earlier days of R 1.* days . [ Goes digging...] Yes, see `help(RNGkind)` which details that R 1.7.0 made a change when "Buggy Kinderman-Ramage" was added as the old value, and "Kinderman-Ramage" was repaired. There once was a similar fix in the very early days of the Mersenne-Twister which is why the GNU GSL has two variants with suffixes _1998 and _1998. So your issue seems like pilot error to me: don't attach the p...

Is there any way to get .SYS device drivers working with wine ? I have just acquired a Franklin eBookMan and want to use it to read. But the Linux program (ebmsync and ebmsync.tk) will not work on my (SuSE 10.1) laptop. -- Andrew "Oh, bother," said the Borg. "We've assimilated Pooh."

I just downloaded TurboDelphi from edn.emarcadero.com (the full 2006 package) and am trying to install it under wine. Installation stops with a message that it needs DotNet 1.11 installed so I downloaded the .Net package from Microsoft. For some reason, this version will not install - I had previously tried .Net 2.0 and .Net 1.1. The link below leads to a file containing the command-line

I am trying to install wine-20050211 on my second system, which runs SuSE 9.2. After much faffing around I finally managed to download and install bison, which allowed ./config to complete.

...orm(rnorm(1000000)),100) The result is the p-value of a goodness of fit test (chisquare test). It should be a uniform random number in [0,1]. However, if this test is repeated, one almost every time gets an number near one (0.99...) This problems happens only by using normal.kind="Kindermann-Ramage" (the default). This bug also appears in all random variate generation that depend on 'rnorm', like 'rgamma'.

...be > worth considering a change. But changing the default RNG definitely > introduces problems in reproducibility, Well "problems in reproducibility" is a bit vague. Results would always be reproducible by specifying kind="Mersenne-Twister" or kind="Buggy Kinderman-Ramage" for older results, so there is no problem reproducing results. The only problem is that users expecting to reproduce results twenty years later will need to know what random generator they used. (BTW, they may also need to record information about the normal or other generator, as well as...
