Sat 25 May 2013 08:50:13 AM UTC, comment #3: I must admit I was a bit confused about the definition of harmonic mean of sets with non-positive values. Wikipedia gives the definition of harmonic mean for positive real numbers. OpenOffice also produces errors with sets including zeros and negatives.

Harmonic means for descriptive statistics (descriptives and frequencies). Calculated in moments.c. I separated counting of harmonic means in a new function void moments_calc_additional.

Thanks for making sure of the definition! I did not have any reliable good sources at hand.
I am going to review the code and do changes for accepting negative values and cheking for any zeros in the dataset.
