The argument 'K' is missing since you are only passing four arguments to
the phi() function, but you defined it with five formal parameters. It
looks like the argument 'j' is not necessary in the function. It is an
unnecessary carry-over from the summation notation and it is never used
in th

This looks like a specific Macintosh error that appears at random intervals.
I get it at random, and unreproducible times. I reported it (or
perhaps a close relative)
to the r-sig-mac list in September 2014.

There are two issues:
1) Damage was done to accuracy in the calculation of t(X) %*% X
Where the mean to SD ratio is large, maybe even of the order of
100 or so, centre that column.
2) pseudo inverse() goes awry with columns of X that are of the
order of large negative (or, I expect, +ve) powers of
That is an adequate solution. It's always better if R package authors don't
hard-code graphics parameters, though.

Hi,
I would like to know if someone has any idea to use RAnalyticFlow and Rstudio
together, i.e., use the nice flowchart system of RAnalyticFlow within the great
interface of Rstudio ? I searched on the internet but without success ...
This would simplify/clarify so much my codes ! :)
Thank for
Hi T.,
Your translation of the formula looks okay, and the error message is about
a missing argument. Perhaps you have not included the necessary arguments
to "phi" in the call to "mls".

Hi, R users-
I'm estimating random effects models with cross-level interactions; I want

Hi everybody,
I am trying to generate the formula shown in the attachment. My formula so far
looks as follows:
phi <- function(w1, w2, j, k, K){
zaehler <- (k/K)^(w1-1)*(1-k/K)^(w2-1)
nenner <- sum( ((1:K)/K)^(w1-1)*(1-(1:K)/K)^(w2-1))
return( zaehler/nenner )
}
Unfortunately something must be w
Thank you for your replies!
I am terribly sorry for the code not being reproducible, is the first time I

To answer to your questions:
How do you know this answer is "correct"?

I have sent turkish real Gdp data (1998-2013) in annex.
Turkey has lived two crises in this period, in 2001 and 2008. You can see
in data.
My problem is to indicate these dates any statistic test as a structural
change or point change.

Thanks for that Ben, I appreciate it a lot.
I have another question if you don't mind taking the time to answer it. I
want to create a subset from dataset called "datafile5" with only the
variables "Date," "PM2.5 mean concentration," "SITE_LONGITUDE," and
"SITE_LATITUDE," dating only in September

Once you have looked at the data and chosen change points to test
based on the data, the tests for change points are invalid (unless you

And no, I am not making this up. Consult any competent statistician.
