Function to compute the geometric mean of a numeric vector
Description
Computes the geometric mean of a numeric vector. It is the n-th root of the product of n numbers, as follows.
y_g = \left(\prod_{i=1}^{n} y_i\right)^{1/n}
for y_i > 0
.
The geometric mean can be used a central position statistics of
a random variable.
