Can I calculcate the percentage of a gamma function area below a cutoff value?
Hi there,
I have some bird flight height data that follows a gamma distribution. The
data (x) goes from 0 to 700 meters (n=1055). The calculated parameters
calculated from the fitdistr(x) are (shape = 5.1379, rate = 0.017541), and
therefore the scale (1/rate) = 57.00929. I would like to calculate the
percentage of the function area that occurs below 50 meters (0-50m).
Is that

Liveness Analysis
...ill either need to regenerate kill flags after regalloc, or
// preferably fix the scavenger to not depend on them).
When looking in TwoAddressInstructionPass.cpp it looks like the pass only
use/update LV when there is no LIS. And there seems to be an experimental
-early-live-intervals option to calculcate LIS before
TwoAddressInstructionPass.
I also noticed that the -early-live-intervals option was added back in 2012.
So I assume that the plans to replace LiveVariables by LiveIntervals
in TwoAddressInstructionPass got some history.
Has there been any evaluation (lately) from using -early-live-i...

Tukey HSD plot with lines indicating (non-)significance
...the compact letter display (CLD) of the multcomp package.
# This shows boxplots (but it is easy to overlay the actual
# observations, using the points() function) and uses letters
# to indicate non-significance.
#
# (Note that (if I have understood everything correctly) this
# doesn't actually calculcate Tukey HSD values (the "Tukey"
# in the glht() call only selects Tukey *contrasts*), but
# the results should be *very* similar.)

Applying a function on n nearest neighbours
...0.4 setosa
For each row, I look at the value of Sepal.Length. I then figure out the
n rows where the value of Sepal.Length is closest to that in the
original row, and apply a function on the values of Sepal.Width to these
rows (typically returning a scalar).
For example, setting n = 5 and calculcating the mean on a slightly
modified dataset, based on the first row (Sepal.Length ~= 5.1):
$ set.seed(1)
$ iris[,1:4]=iris[,1:4]+runif(150)/100
$ x=iris$Sepal.Length[1]
$ (pos=which(order(abs(iris$Sepal.Length-x)) %in% 2:6))
[1] 18 26 40 42 52
$ mean(iris$Sepal.Width[pos])
[1] 3.086595
Now, I c...

Liveness Analysis
Where is the liveness analysis pass? I have been looking for days but
cannot find anything.
I just want to know transfer variables in and out of basic blocks, that are
calculated using simple data flow equations.
Thanks!
