Bug in truncgof package?
...pers,
I was testing the truncgof CRAN package, found something that looked
like a bug, and did my job: contacted the maintainer. But he did not
reply, so I am resending my query here.
I installed package truncgof and run the example for function ad.test. I
got the following output:
set.seed(123)
treshold <- 10
xc <- rlnorm(100, 2, 2) # complete sample
xt <- xc[xc >= treshold] # left truncated sample
ad.test(xt, "plnorm", list(meanlog = 2, sdlog = 2), H = 10)

my own function given to lapply
Hi
It seems, I just miss something. I defined
treshold <- function(pred) {
if (pred < 0.5) pred <- 0 else pred <- 1
return(pred)
}
and want to use apply it on a vector
sapply(mylist[,,3],threshold)
but I get:
Error in match.fun(FUN) : Object "threshold" not found
thanks for help

vector vs array
Hi!
OK, I'm trying to select some "useful outliers" from
my dataset: I defined 11 "treshold" values (1 for each
level of a variable (sampling site) as follows:
tresholds<-function(x)
{
tapply(x,mm$NAME,FUN=mean ,simplify = T, na.rm=T)->med
tapply(x,mm$NAME,FUN=sd ,simplify = T,
na.rm=T)->standev
standev+med
}
tresholds(mm$chl)
Now I'd like to select those values...

The second and third question concern the output of the printcp() function.

What exactly are the cps in that sense here? I assumed them to be the treshold
complexity parameters as in Breiman et al., 1998, Section 3.3? Are they the same
as the treshold niveaus of alpha? I have read somewhere that the cps here are
the treshold alphas divided by the root node error. Is that true?

polygon
Dear all
In order to clearly mark values wich are larger than a treshold value, I
would like to color the surface below the line given by plot (yy~xx). To
color is only the surface between abline (treshold) and yy if they are
larger than the specific limit. I guess I can use the function polygon,
but I can not find any valuable solution.
I'm grateful to you for...

Linux freezes on large file transfers
...y to copy
files larger than say <550 ~650MB using MD 10, my linux box freezes and must
be rebooted. I can FTP the same file(s) perfectly fine to other PC 's on my
home net. Small volumes of files work fine as well as ISO images, the box
seems to lock up only after it passes some type of treshold treshold. I am
not sure what to do here. I have installed of the latest SMB packages for MD
10. The problem still persists.
Is there some config parameter that I must change?

Milliwatt Analyzer available
...but can be passed
as argument. The periode duration must be a mulitple of 0.5 ms,
thus the valid frequences are: 2000 Hz, 1000 Hz, 666.666666667 Hz,
500 Hz, ...
Furthermore the application computes the ripple on that tone.
In order to detect audiogaps and short noise on the line, one can
define a treshold and a timeslice duration (typically 1s to 0.1s), and
the application will compute the ripple for each timeslice and count the
timeslices with a ripple greater than the given treshold.
Thus the application is a tool to verify the line quality, e.g. for
least-cost-but-not-too-bad-line routings.

cram-md5 and users maintaining their own passwords?
...t will support cram-md5

Has anyone created setups where the passwd databases reside in the
individual users home directories?
Is it possible to persuade dovecotpw to update the passwd databases
automatically. Having to use a text editor to paste in the passwords
sets a high user treshold on using the cram-md5 authentication
mechanism.
Thanx!

mixed-effects models for left-censored data?
Dear R-helpers,
excuse me if this is not exclusively an R-related question.
I have data from a nested design, both temporally and spatially, and the reponse variable of interest is left-censored. That is, only values > "some treshold" are available, otherwise "LOW" is reported.
Are there ways of building a linear model with both fixed and random effects, when the response variable is censored? Can the tobit model be modified to do this? Does anyone have experience with this type of dataset?
Help is much apprec...

Replacing for loop with tapply!?
Dear all,
We have a large data set with temperature data for weather stations
across the globe (15000 stations).
For each station, we need to calculate the number of days a certain
temperature is exceeded.
So far we used the following S code, where mat88 is a matrix containing
rows of 365 daily temperatures for each of 15000 weather stations:

n <- 2

So, which is the prefered solution to send this data to NUT?
And my last question:
Is it possibel to SET values from NUT in the "24 V DC modular ATX PSU"?
I mean something like Alarm, Tresholds and such?

[LLVMdev] [PATCH] Split LoopUnroll pass into mechanism and policy
...ell. Is that wanted?
Overall, I've really only moved code, so behaviour should be unchanged. The
only functional change I think I made, was that the old code checked to see if
the terminator instruction of the latch block was a conditional branch first,
before looking at the trip count and the treshold. Since that check moved
together with unrollLoop, it is done a bit later. However, AFAICS, none of the
code (getTripCount, code size estimation) actually depends on this check, so it
shouldn't change anything in the end.
Lastly, the (original comments) say "This pass will multi-block loop...
