Geometric mean with zeros

WebJan 19, 2024 · The geometric mean from Wiki is: "The geometric mean is defined as the nth root of the product of n numbers" so for 2 numbers its simply the square root of their product. The nth root in my case will vary on each row depending on how many of the values are non-zeros in them. In my example below the top 2 rows of the results column … WebMar 29, 2024 · The formula of the gemetric mean is: So you can easily write an algorithm like: import numpy as np def geo_mean (iterable): a = np.array (iterable) return a.prod ()** (1.0/len (a)) You do not have to use numpy for that, but it tends to perform operations on arrays faster than Python. See this answer for why.
