Hello everyone,
I'm stuck with naming once again.
I'm developing a module for approximate descriptive statistics. I'm
trying to follow the interface of Statisitcs::Descriptive::Full as close
as possible.
As an exception, I've added central and standardized moments:
central_moment($n); # == <(x-<x>)**n>
std_moment($n); # == <(x-<x>)**n>/sigma**n
-- but these seem unambiguous enough. (Or should I stick with
standardized_moment() instead?)
But now, I'm looking for a good name for a method that integrates
arbitrary function over part of the sample. My current API looks like
$stat->sum_of($coderef, $min, $max);
# add up $coderef->($x)
# for part of sample between $min and $max
$stat->mean_of($coderef, $min, $max);
# trimmed expectation
# of $coderef->($x)
$stat->integral_of($coderef, $min, $max);
# integrate f(x)*P(x)*dx
# where P is probability density (not done yet)
Does sum_of(...) count as a good, descriptive name? What about others?
Note: I'm NOT proposing any changes to Statistics::Descriptive itself!
However, I'd like to be consistent with the rest of the pack
(S::D::Full, S::D::Discrete, etc) for as long as possible in the future.
