[Insight-users] Are these metrics based on "correlation ratio"?

[Cory Quammen]

Pinpress,

I don't have an answer for your first question, but in regards to
checking which version has a class, you can view the documentation for
version 3.8 by going to

http://www.itk.org/Doxygen38/html/classes.html

It appears this version has the classes you asked about.

To see the documentation for a particular version of ITK, replace 38
with the major and minor version numbers concatenated together, e.g.,
316 for 3.16.
