I am wondering if something will replace the deprecated CurveFitter classes? I
looked around on the mailing list and Jira but did not see anything. I am

I have not settled on a fit/cost function and haven'

Hello,
I may be missing it somewhere, but I am surprised there is no function for
scaling arrays in MathArrays.java or somewhere else.

- Shall I add it?
Thanks,

Ted,
I am not sure I understand the problem with the fixed number of components. My
understanding is that CM prefers immutable objects. Adding a component to an
object would require reweighting in addition to modifying the component list.

Gary,
I have wondered about the public scoping of arrays myself for that same reason.
I also write image processing code, and the arrays can be quite large,
especially if the processing is in three dimensions.

Gilles,
I think it will be difficult (for me, at least) to provide a general method for
testing sampling across all multivariate distributions. I imagine it can be
done, but I would prefer for now just to make it an abstract method and expect
