How can I test if time series residuals' are uncorrelated ?
Ok I made Jarque-Bera test to the residuals (merv.reg$residual)
library(tseries)
jarque.bera.test(merv.reg$residual)
X-squared = 1772.369, df = 2, p-value = < 2.2e-16
And I reject the null hypotesis (H0: merv.reg$residual are normally
distributed)
So I know that:
1 - merv.reg$residual aren't independently distributed (Box-Ljung test)
2 - merv.reg$residual aren't indentically

R package with Java source code
Dear All,
Are there any plans around that "R CMD INSTALL
some_package_containing_java_source code" supports Java source code
compiling in future versions of R similar to compiling C/C++ and/or
Fortran sources in the src directory?
Best regards
Adrian

Combinatorial Optimisation
Hi
I am looking to perform a discrete mean-variance optimisation, specifically to maximise the ratio of portfolio mean over portfolio standard deviation for a portfolio of several hundred stocks through discrete position size holdings in each stock, where all position sizes must be elements of a small finite set of integer amounts which include zero.
I don't think any of the standard R

tseries contains a class for irregularly spaced time series
...quot;. It provides some basic functionality such as reading
and writing irregular time series from files, or plotting, printing,
subscripting, and interpolating irregular time series. This is a first
version of the class "irts" and I very much welcome feedback.

Modified ARMA function
R-guRus ,
ARMA function in tseries, seems to be calculating the AR coeff 's as
coef <- lm(xx[,1]~xx[,lag$ar+1])$coef [*snipped* from around line
77,]
I'd like to modify this model with another term somewhat in these lines
lm(xx[,1] ~xx[,lag$ar+1]+mvgsignal)$coef
where mvgsignal is a moving average signal based on some indicators, the
question
is could i simply hack into

Re: R-help digest, Vol 1 #80 - 14 msgs
...nce the number of "independent
observations" is considerably smaller than 100. Therefore asymptotic theory might be a
bad approximation and small sample effects might lead to severe size distortions.
Maybe someone can explain more formally whats going on here?
