I misunderstand the definition of Canberra distance in R.
On Internet and in function description pages of dist() from stats and

But in use, through simple examples, we find that the form

Thank you for all your responses.
For the font problem, all I need is someone to tell me *which* font libraries I

Another approach that usually works well is to use the option: algorithm =
"port". This uses the "nl2sol" routine.
foo.nls <- nls(var~Emax*(Dose^hill)/((EC50^hill)+(Dose^hill)),
start=list(Emax=-4,EC50=269,hill=1), algorithm="port", trace=T,data=foo)
This generally has more robust convergence

No. Excel is notorious for this.
Thats what is frustrating meI've done a lot of reading, but there doesnt

Short answer: because some of the data you want to use

Here is a solution using SVD:

I am looking for a function for MI (mutual information) for
continuous variables X, Y.
I prefer not to discretize X,Y as it leaves the problems of optimal
bin number etc.
Can any one give a pointer to calculate mutual information using
Gausian kernel estimator for two continuous variables ?

Thank you guyz. your codes gave me the results I was looking for. And thanks
for the reference suggestion. Lastly, how do I code the frequency of heads?

THANKYOU guyz! yes, Jim's code was right (it was similar to someone
elses)I somehow missed his reply!
Yes, that was exactly what i was looking for. lastly, how do i find the
frequency of heads perhaps?

Dear R users,
I need to calculate the univariate impulse response function for a series of
data. Unfortunately the vars package does not support univariate analysis. If I
try to evaluate a single series like this:
VAR(y=xres,p=1,type="none",ic="AIC")
the result is
Error in VAR(y = xres, p = 1,
sum(toss == 1) /length(toss) # assuming heads == 1

Here is a more general R function to solve "any" linear system (under/over
determined):
ls.min <- function(x, y) {
# solves: x %*% b = y
d <- svd(x)
# min-norm solution
b.min <- d$v %*% diag(1/d$d, length(d$d)) %*% t(d$u) %*% y
return(b.min)
}

[Yes, this is related to a homework problem, but is not the problems
itself.]
In my mathematical statistics class, we've just learned about properties
of estimators, and I can now solve manually problems like this:
A sample of size n = 16 is drawn from a normal distribution where sigma
= 10 but m

Daniel, thanks for your suggestion. So, it's just done like this:

Thanks, again.
