search for: indistinguish

Hi! is there a way in R to check whether the outcome of two different experiments is statistically distinguishable or indistinguishable? More preciously, I used the wilcoxon test to determine the differences between controls and treated subjects for two different experiments. Now I would like to check whether the two lists of analytes obtained are statistically distinguishable or indistinguishable I tried to use a equivalence...

Hello I'm sorry if this suggestion/correction was already made but after a search in devel list I did not find any mention of it. I would just suggest to add a warning or an exemple for the help-file of the function unique() like "Note that unique() compares only identical values. Values which, are printed equally but in facts are not identical will be treated as different."

Hi How do I generate all ways of ordering sets of indistinguishable items? suppose I have two A's, two B's and a C. Then I want AABBC AABCB AACBC ABABC . . .snip... BBAAC . . .snip...

...sers that don't have html-based audio playback features. If you follow up with me via personal email, I'll be happy to try to debug the situation with you. I wasn't sure what bit rate was appropriate for "Very high quality" with opus, i.e. something that was "commonly indistinguishable from a WAV file". Any advice on that is appreciated. -john

...s. There is the potential for API users to misinterpret the state being returned since the return variable was of type FLAC__StreamDecoderState, but the value being returned was FLAC__StreamDecoderInitStatus. When FLAC__STREAM_DECODER_INIT_STATUS_ALREADY_INITIALIZED was returned in this case it was indistinguishable from FLAC__STREAM_DECODER_OGG_ERROR. Is there somewhere that I can push the patch so that it can easily be pulled into the repository or does one of the maintainers just apply the patch and attribute the credit in the commit message?

...code are a mixed blessing which personally I'd opt to not have, on balance. Being German I can understand that people may want umlauted characters in their variable names, but where this catches on, it's just a matter of time that people get characters into their code that are different but indistinguishable in the font they use (I've seen this with \H{o} rather than a \"{o}), and mega-personmonths are wasted puzzling over tracking down these problems. While many packages are used in-house at least initially, making a package is a step towards releasing it, so I'd anticipate that havi...

Dear all, How does the effect() function in the effects package calculate effects and standard errors for glm quasipoisson models? I was using effect() to calculate the impact of increasing x to e + epsilon, and then finding the expected percent change. I thought that this effect (as a percentage) should be exp(beta*epsilon), where beta is the appropriate coefficient from the model, but

...inct ID numbers with different BB in a module. As long as the module's IR hasn't changed in any way whatsoever, I'd like to be guaranteed to always generate the same ID <--> BB mapping. Or if the mapping is ambiguous, because two or more mappings between BB's and ID's are indistinguishable (isomorphic?), I'd like to be sure I at least can reliably re-obtain some mapping in that equivalence class. This seems related to a debate / bug-report <https://llvm.org/bugs/show_bug.cgi?id=16043> regarding the arbitrary nature of (pseudo?) labels in LLVM assembly. E.g.,*"; l...

Allowing for messages in non-ASCII encodings would probably be a good idea, but I think allowing non-ASCII variable names is dangerous. -- Regards, Bj?rn-Helge Mevik

...-- but I don't think that's the right approach for two reasons: 1) It will be a *very* narrow canonicalization that only works with overly specific sets of casted pointers. 2) It doesn't effectively move us toward the optimizer treating IR with different pointee types for pointer types indistinguishably. Some day, I continue to think we should get rid of the pointee types entirely. To see why #1 and #2 are problematic, assume another round of inlining took place and we suddenly had the following IR: AFAICT, this is the same and we still don't have a good canonicalization story.

R-help(ers), Does anyone know of an R function available for calculating a confidence interval for a Spearman correlation? If no such resource is available, is using the confidence interval from a Pearson correlation a reasonable proxy if the vectors come from normal distributions (i.e. likely indistinguishable from the true confidence interval in error bars of an autocorrelogram or correlation plot)?

Hi all, Is there a way to force llc to generate movupd instruction instead of movapd for x86 target ? I know that movapd is more performant, but I would like to measure degradation when alignment constraints are not met.
