stochastic process transition probabilities estimation
..._{t-l_1}, X_{t-l_2}, ...,
X_{t-l_k} ], and taking the factors of Y_t and of its margin without
the first component I think I'm done. Unfortunately, factor, sort,
unique all work only with univariate data.
Any other suggestion will be very appreciated...

apply'ing cut to a data.set column
Hi all,
there is probably something I'm still missing about how R
manipulates multivariate data. I have a dataset in which, for various
tuples of a set of 4 parameters, a value of interest is stored:
p1 p2 p3 p4 v

0 1 1 0 0.6124

testing for a distribution of probability
Hello!
I have several variables. Each of them has a different distribution. I was
thinking to use a Generalized Linear Model, glm(), but I need to introduce
the family. Do you know if R has any tests for matching data to any
distribution ( I am aware of shapiro.test).
All the best,

portfolio.optim and assets with weigth equals to zero...
...io.optim returns an asset with weight equals
to zero.
If I do a portfolio.optim with 3 assets, without the asset with weight
equals to zero,
it returns a completely different result.
That's I would expected the same weights as the run with 4 assets.
Below the code.
Thanks in advance,

There is the package 'financial', with the function 'cashflow', calculating
irr for regular intervals.
So I developed xirr, managing irregular intervals, that's accepting a vector
