Maximum Likelihood Estimation Poisson distribution mle {stats4}
Hi everyone!
I am using the mle {stats4} to estimate the parameters of distributions by
MLE method. I have a problem with the examples they provided with the
mle{stats4} html files. Please check the example and my question below!

bbmle "Warning: optimization did not converge"
I am using the Ben bolker's R package "bbmle" to estimate the parameters of a
binomial mixture distribution via Maximum Likelihood Method. For some data
sets, I got the following warning messages:
*Warning: optimization did not converge (code 1: )
There were 50 or more warnings (use warnings() to see the first 50)*

Maximum Likelihood estimation of KB distribution
Hi, The following distribution is known as Kumaraswamy binomial Distribution.

browsers slowing Centos 7 installation to a crawl
My video problems mentioned in a previous thread are gone,
though I do not know why.
Now my problem is that whenever I have a
browser open and an internet connection,
my Centos 7 slows to a crawl.
Chromium seems to be the least bad.
Sometimes it slows to the point that I cannot even move the mouse.
Even switching between virtual terminals takes a while sometimes.

DECLARING A PANEL VARIABLE???

I am working on a panel data, my data are clustered/grouped by the variable

declaring migration bankruptcy
I joined a project recently that has 2 years worth of migrations. It
is about to go into production and I am wondering if we should
consider clearing out most of the history. A poor decision made early
on has caused the project to have about 20 custom plugins (all of
which really belong in the application). One task involved in moving
the code out of plugins involves all the migrations. The

[LLVMdev] Forward-declaring defs in TableGen
Is there a way to forward-declare a def in TableGen and then define it?
For example:
def foo : Foo;
def bar : Bar {
let FooThing = foo;
}
def foo : Foo {
let BarThing = bar;
}
This causes a multiple-definition error in TableGen.

[LLVMdev] Declaring constant global variables
Hiya,
I want to declare a constant global variable as:
@.str = private constant [4 x i8] c"%f\0A\00", align 1 ; <[4 x i8]*> [#uses=1]
I guess I should firstly declare an arrayType object, then declare a
GlobalVariable object.
I have two problems:
1. What element type I should set for the arrayType?
2. How to set the constant value as :c"%f\0A\00"
Cheers,
Zheng

Can I do this in my own pass module?
Because the string is actually depended on the type of a value object.

I imagined you'd want to recognize loops, not scopes. Sounds like a
backend kind of optimization type thing, just detecting values that
don't escape the loop. (this would catch cases

I don't know the mid-level optimizers especially well - I doubt
there's a thing that does exactly what you need - but a combination of

S4 Reference Classes: declaring public and private methods
Dear list,
is there a way to declare public and private methods in S4 Reference
Classes? If not, are there plans to add such a feature?

RFC: Declaring "foo.bar" as nonS3method() ?!
And my non-cross-posted cross-posting:
"Dear Martin,
Thank you for addressing this issue. Introducing a nonS3method() directive in NAMESPACE seems a reasonable solution. It could replace export() for functions with "."s in their names.
Best,

declaring nonS3method
If Martin's proposal for declaring non-S3 methods in NAMESPACE is
feasible, it would be very helpful. The packages we support have
multiple examples of unfortunately named functions non-S3 functions, so
creating a route for migrating them into compliance would be great.
