dw statistic
...for spending your time replying to my mail. I'm
very impressed with the speed that my question was answered.
I'm new at R (about two weeks) and reading your mail made me realize that it
was indeed a question of vectors of different lengths. I thinked that I
could create a function ("carfun") without creating a "x" vector, since the
only purpose of that function is to be integrated right away in the same "x"
(I re-posted my function again at the end).
But now I have another question: since "x" must be of "(dw-eigen)"'s
length, how...

warning message
Hello everybody.
I would like to pose a question regarding a warning message after running
a function of my own. The function I created for computing the p-value of
the dw statistic has a command line like this:
»dwf0 <- function(dw,eigen) { carfun <- function(x) {
(prod(1+2*(eigen-dw)*1i*x)^(-1/2)-prod(1-2*(eigen-dw)*1i*x)^(-1/2))/(1i*x) }
; 1/2+integrate(f=carfun,lower = 0,upper = Inf,
subdivisions=10000)$value/(2*pi) }
, with arguments "dw" as a real and "eigen" as a vector.
After I run:
»dwf0(1.314416,c(3.44...
