Function to compute the harmonic mean of a numeric vector

Description

Computes the harmonic mean of a numeric vector. It is the inverse of the mean of the recriprocals of n numbers, as follows.

y_h = \frac{n}{\left(\sum_{i=1}^{n} \frac{1}{y_i}\right)}

for y_i \neq 0. The harmonic mean can be used a central position statistics of a random variable.

Usage

hmean(v)

Arguments

v	is a numeric vector

Details

Notice that can only be computed for values different from cero.

Value

This function returns the harmonic mean, a numeric scalar.
