implementing Maximum Likelihood with distrMod when only the PDF is known
...uels
I am trying to use the (very nice) package distrMod as I want to
implement maximum likelihood (ML) fit of some univariate data for which
I have derived a theoretical continuous density (pdf). As it is a
parametric density, I guess that I should implement myself a new
distribution of class AbscontDistributions (as stated in the pdf on
"creating new distributions in distr"), and then use MLEstimator() from
the distrMod package. Is that correct or is there a simpler way to go?
Note that I want to use the distr package because it allows me to
implement simply the convolution of my theoretical...

request for comments --- package "distr" --- S4 Classes for Distributions
Hello,
after some discussions with Martin Maechler and Josef Leydold (WU Wien),
we have felt the need for some package that should allow for an
object-orientated
approach to distributions.
Our small group at Bayreuth now has developed a package "distr" which
tries to fill this gap, implementing distributions by means of
S4--classes.
A mother class "Distribution" is

solution of convolution equation
Hello,
May be somebody can help me...
I am trying to find a solution of a convolution equation using fft (and
unfortunately I do not have a good background for this).
So I am just trying to figure out how it can be implemented in R. I have
two multidimensional independent variables X and Z
and I know their densities fx and fz, which are multidimensional arrays.
So I have to find the density of

calculate quantiles of a custom function
Hi,
I guess that my problem has an obvious answer, but I have not been able to
find it.
Suppose I create a custom function, consisting of two beta-distributions:
myfunction <- function(x) {
dbeta(x,2,6) + dbeta(x,6,2)
}
How can I calculate the quantiles of myfunction?
I have not seen any continous function treated in the docs, and applying the
"quantile function" gives me an

New package: distr
We would like to announce the availability on CRAN of a new package distr .
It is to provide a conceptual treatment of random variables (r.v.'s) by
means of
S4--classes. A virtual mother class "Distribution" is introduced.
All distributions of the "base" package are implemented as subclasses of
either "AbscontDistribution" or "DiscreteDistribution".

convolution of the double exponential distribution
Is there any R function that computes the convolution of the double
exponential distribution?
If not, is there a good way to integrate ((q+x)^n)*exp(-2x) over x from
0 to Inf for any value of q and for any positive integer n? I need to
perform the integration within a function with q and n as arguments. The
function integrate() is giving me this message:
