Hi there,
I misstyped frnd(32.5,14.2,1,1) and yet I got an output.
What is the interpetation of a d.f. when it is non-integer??
Thanx!!

It all depends on the underlying statistic. See http://en.wikipedia.org/wiki/Degrees_of_freedom_(statistics)#effective_degrees_of_freedom

From the language functionality point of view, they don't mean
anything. They just happen to be valid characters for method names,
and people can use them to give more readability to their code.

**method method**In JS:TGP, Crockford defines a method called method:
"Throughout the book, a method method is used to define new methods.
This is its definition:
Function.prototype.method = function (name, func) {
this.prototype[name] = func;
return this;
};
It will be explained in Chapter 4."
So far, so good.
Then, in Chapter 4 in the section "Augmenting Types" he goes on:
"For example, by augmenting Function.prototype, we can make a method
available to all functions:
Function.prototype.method = function (name, func) {
this.prototype[name] = fun...

**chi2pdf degrees of freedom**I am trying to convert a chi-square error surface to a pdf using chi2pdf. I have a series of measurements (dataMeas) and corresponding estimates (dataEst) which I generate over a grid using a model of the measurement system (awgn with sigma "sig" assumed for everything). I compute the normalized chi-square error surface for each grid point as follows:
resid = (dataMeas-dataEst(:,gridVal));
csErr(gridVal) = (resid*resid')/(sig^2*numDf);
where numDf is the number of degrees of freedom computed as the number of samples in the data vectors minus the number of parameters used...

**Template systems**I'm looking for a good idea or ready library for templates. HTML with
PHP isn't the best solution (it's more difficult for end-users of CMS
to edit them). Perhaps, everything I need is:
- variables - e.g. {var}
- sections or conditions (some elements won't be printed out)
- loops or selecting fragments*
- cache (recommended for speed)
The template system must be fast and efficient. Most probably I will
create own library for CMS requirement. However, i think about
existing scripts, e.g. XT (XHTML Templates) and OPT (Open Power

**question about the system method**Hi, all
I want to use system method to run a background process, like
system("ruby deamon.rb") # the deamon.rb runs a dead loop
When my main process ends, I want to end the background process
too.
How can I do it?
If I can get the pid of background process, I can use
Process.kill. But the system method dosen't return the pid.
Does anyone here know the solution?
Thank you

**Euler method for a system**I have the two equations:
dx/dt = -2x
dy/dt = 5x - y
x(0) = 5
y(0) = 1
for t values between 1 and 200
I want to use the Euler method to solve this system and then graph each x and y vs t.
Could someone point me to a code that could do this? Don't worry, I don't need to come up with the code myself, so helping me out here isn't contributing to cheating in anyway. Thanks,

**linhyptest and degrees of freedom**Happy new year all,
I'm using nlinfit to parameterize an exponential function
and want to run an F test on the fit of the model. It
appears that I can do this with linhyptest, but the P values
returned by linhyptest are much smaller than expected. I'm
confused about what degrees of freedom for error i should be
specifying. Does this appear correct for a 2 parameter model?:
expon_fit = @(b,x) b(1)*exp(b(2)*x);
beta=[guess1, guess2]
[b,r,J,COVB]=nlinfit(X,Y,expon_fit,beta);
dfe=length(Y)-2;
H=[1 0;0 1];
c=[0;0];
[p,t,r]=linhyptest(b,COVB,c,H,dfe);
thanks,
Jeff

Work category 1 F=14.95 with 14, 1074DF
Time F=317.06 with 2,537DF
Interaction Work category by Time F=4.54 14,1074DF
There were not an equal number of observations in each cell.
If I run separate univariate anovas for each of the IV for work

**Passing a method(reference) to an other method and calling the method.**I have a staight forward question. Is is posible to pass a method as a
parameter and call the passed
method from within the other method? Something like the apply function
in Python where can specify which fuction with what parameters is
called (apply("thisMethod", arg1)).
The reason I ask this is because I want to implement a callback
mechanism. How can this be done or is there an other way to implement
a callback mechanism where it's posible to call an arbitrary method?
Thanks.

**System.out and System.err**I think we all assume that access to System.out and System.err is
thread-safe; if we write to them from more than one threads, the worst
that will happen is output getting interleaved but not lost, nor will
exceptions be caused by unsynchronized access (e.g., we don't expect
internal bufferr-copying routines to get confused.) Looking, though,
I can't find this guarnteed anywhere. Can anyone point to an offical
statement about it?

**calling a method from a method**Hi
I have a a function with several methods. For simplicity it looks a bit
like this:
super.prototype.aProperty="HELLO";
super.prototype.returnValue = function () {
return 2;
}
super.prototype.aMethod = function () {
var a = this.returnValue()
alert(a)
}
function super() { }
theObject= new super;
theObject.aMethod();
How can I call a method from within a method? In other word how can I
make the "this" keyword refere to the object and not the method?

**Degree of freedom in Neural Networks**Hi Neural Network people,
I have a question about some posts on the Newsreader concerning the degree of freedom for adjusting the weights.
The following conditions for adjusting the weights properly is made:

with
Neq = N*O = N % Number of training equations
Nw = (I+1)*H + (H+1)*O % Number of unknown weights to estimate
Nw in this case applies to I-H-O structure. Does the rule Neq>Nw also apply to structures with more hidden Layers? I am not asking about the rule for calculating nw for a multilayered network.

There are others like this, too.
The naming-convention seems to be that a (! "bang") method exists
only if there is a corresponding (non-bang) method which doesn't
modify the receiver.

**degrees of freedom in proc mixed**Hi All,
I am having some difficulty understanding the way that proc mixed is

degrees of freedom add up to more than the number of replicates

replicates, respectively. The response of each replicate is measured
twice (the repeated component). I also have several covariates and
their interactions with the treatment (irrig) and the repeated effect
(season) in the model.
