Asymmetry and kurtosis coefficients
Hello everybody, I'm studying descriptive statistics with R and I want to know how to calculate the asymmetry and kurtosis coefficients of a sample using R. I'll appreciate some help.

TO SYMMETRY AND ASYMMETRY-----NOW ADD SUPERSYMMETRY
Open Letter to Developers, Is there any way you can cut through the mob scene at Homeland Defense with a powerful new encryption/decryption formula? The government cryptography bunch are stuck in symmetry and asymmetry and are deaf/dumb/blind to supersymmetry. When it's so easy to line up a supersymmetrical hypercube fractal-to-fractal, pair-to-pair, quantum-to-quantum and slice through

Fluctuating asymmetry and measurement error
Hi all, Has anyone tested for FA in R? I need to seperate out the variance due to measurement error from variation between individuals (following Palmer & Strobeck 1986).

[LLVMdev] [RFC] How to fix sqrt vs llvm.sqrt optimization asymmetry
Hello everyone, The particular motivation for this e-mail is my desire for feedback on how to fix PR17758; but there is a core design issue here, so I'd like a wide audience. The underlying issue is that, because the semantics of llvm.sqrt are purposefully defined to be different from libm sqrt (unlike all of the other llvm.<libm function> intrinsics) (*), and because autovectorization

[LLVMdev] [RFC] How to fix sqrt vs llvm.sqrt optimization asymmetry
Hi Hal, all. I'm not sure why llvm.sqrt is 'special'. Maybe because there is a SSE packed sqrt instruction (SQRTPS) but not e.g. a packed sin instruction AFAIK. As mentioned in a recent mail to this list, I would like llvm.sqrt to be defined as NaN for argument x < 0. I believe this would bring it more into line with the other intrinsics, and with the libm result, which is

attach/detach asymmetry
Is there a good reason why arguments to 'attach' and 'detach' differ so much? Yes, I know this is the documented behaviour, it just seems to violate the principle of least surprise. Examples: file = "foo.RData" df = data.frame(x=1:10,y=1:10) attach(file) # attaches the RData file 'foo.RData' attach(df) # attaches the object df Not surprising in an

Quelplot
Hi all, Does anyone have an R implementation of the queplot (K.?M. Goldberg and B.?Iglewicz. Bivariate extensions of the boxplot. Technometrics, 34(3):pp. 307?320, 1992)?

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi all, I propose simple improvement for MergeFunctions pass, that reduced its complexity from O(N^2) to O(log(N)), where N is number of functions in module. The idea, is to replace the result of comparison from "bool" to "-1,0,1". In another words: define order relation on functions set. To be sure, that functions could be comparable that way, we have to prove that order

Inf +1i vs 1+Inf*1i
Hi If I have a <- Inf + 1i then Re(a) is Inf, and Im(a) is 1, as expected. But if b <- 1 + Inf * 1i, then Im(b) = Inf , as expected, but Re(b) = NaN, which I didn't expect. Why this asymmetry?

About the Skew Student distribution
Hello everybody, I need your help about the package SN and the skew student distribution. Il will be very grateful if I have the solution. I construct a stochastic model with a white noise not gaussian but following a skew student distribution. I fit the noise on monthly data to obtain the four parameters. The question is : how to annualize the parameters to use my model for simulate daily data

I'm not going to argue at length about it, but it is worth thinking about. The only practical downsides of void are when newcomers take C's syntax for functions with no arguments a little

[LLVMdev] MergeFunctions: reduce complexity to O(log(N))
Hi Stepan, This looks interesting! Some high-level comments: - Please post the patch untarred next time. Also, I'm not sure if it's typical to provide supporting documents in .doc format; while many of us probably have access to Word, a more portable and email-friendly format (like text, markdown or rst) is probably better. - Have you profiled this? What's the speedup? I

Reg: Throughput b/w domU & dom0
Hi all, I used netperf to measure throughput between dom0 & domU. The throughput between dom0 -> domU was 256.00 Mb/sec domU -> dom0 was 401.15 Mb/sec. The throughput between dom0 & domU seems to be very asymmetry. To my surprise the throughput between domU -> dom0 is more. The value which I specified are consistent values. Is
