The arithmetic mean of a log distribution is equal to the log
of the geometric mean of the linear distribution. It is appropriate
to calculate and report the arithmetic mean of a log distribution
when the distribution is log-normal. Since this is frequently the
case, it is desireable to have the ability to calculate either arithmetic
or geometric means (i.e., be able to calculate an arithmetic mean of
a log distribution with and without conversion to linear). I hope
that I have added to the confusion on this point.
