Estimate "between-axes" vs "within-axes heterogeneity of multivariate matrices
...d answer this question? Some relative/comparative (preferrable simple and intuitive) measure(s)? Something that would graphically perhaps give an indication without time-consuming clustering, sampling or whatsoever processing? Even though the above mentoined authors mention some measure for the assymetry of the yielded compoenents ( uncentered -> unipolar, centered -> bipolar) I find the concept a bit hard to understand. Isn't there a quick way (function) to just say (with numbers of plots of course) "well, it seems that the data are heterogenous looking at between- axes" or...

r documentation rugarch egarch
...tp://r.789695.n4.nabble.com/RUGARCH-eGARCH-and-variance-targeting-td4634896.html someone proposes to read the "vignette on how the unconditional variance is calculated for the eGARCH model" I don`t know what is meant by vignette. The R-built-in help function tells me about eGARCH: "assymetry term: gamma1" Thanks a lot R-help. This is relly a lot of information. I`d like to find out about the eGARCH model notation used in R, the settings and estimation techniques that are used and/or can be configured in this case, ... When searching the internet I`ve also not been very successfu...

[PATCH tip/core/rcu 21/21] drivers/vhost: Remove now-redundant read_barrier_depends()
...s, READ_ONCE is now asymmetrical with WRITE_ONCE. I can read a pointer with READ_ONCE and be sure the value is sane, but only if I also remember to put in smp_wmb before WRITE_ONCE. Otherwise the pointer is ok but no guarantees about the data pointed to. It would be better if the API reflected he assymetry somehow. > --- > drivers/vhost/vhost.c | 7 +------ > 1 file changed, 1 insertion(+), 6 deletions(-) > > diff --git a/drivers/vhost/vhost.c b/drivers/vhost/vhost.c > index 33ac2b186b85..78b5940a415a 100644 > --- a/drivers/vhost/vhost.c > +++ b/drivers/vhost/vhost.c > @...

[PATCH tip/core/rcu 21/21] drivers/vhost: Remove now-redundant read_barrier_depends()
Because READ_ONCE() now implies read_barrier_depends(), the read_barrier_depends() in next_desc() is now redundant. This commit therefore removes it and the related comments. Signed-off-by: Paul E.
