Steven, this seems like a reasonable suggestion (though I would expect someone else will immediately suggest a harmonic mean as well). Is this within the scope of what you were trying to do with the statistics module? |

To complicate things further... I implemented a geometric mean on my own, and then I figured out what I really want is a *weighted* geometric mean, so I implemented that for myself. If you'd want to include that, that'll be cool. Actually I'm not sure if the goal of the `statistics` module is to be comprehensive or minimal. I'm hoping it's meant to be comprehensive. But then I'd guess there would be a lot of things you'd want to add except my little feature. |

And of course, if the goal of the `statistics` module is to be comprehensive, one should ask himself what should be the difference between this new module and a mature statistics module like `scipy.stats`, and whether we should try to copy the features of off `scipy.stats`. |

Choice of algorithm is a bit tricky here. There are a couple of obvious algorithms that work mathematically but result in significant accuracy loss in an IEEE 754 floating-point implementation: one is `exp(mean(map(log, my_numbers)))`, where the log calls can introduce significant loss of information, and the other is `prod(x**(1./len(my_numbers)) for x in my_numbers)`, where the `**(1./n)` operation similarly discards information. A better algorithm numerically is `prod(my_numbers)**(1./len(my_numbers))`, but that's likely to overflow quickly for large datasets (and/or datasets containing large values). I'd suggest something along the lines of `prod(my_numbers)**(1./len(my_numbers))`, but keeping track of the exponent of the product separately and renormalizing where necessary to avoid overflow. There are also algorithms for improved accuracy in a product, along the same lines as the algorithm used in fsum. See e.g., the paper "Accurate Floating-Point Product and Exponentiation" by Stef Graillat. [1] (I didn't know about this paper: I just saw a reference to it in a StackOverflow comment [2], which reminded me of this issue.)

On the other hand, apparently `exp(mean(log(...)))` is good enough for SciPy: its current implementation looks like this: def gmean(a, axis=0): a, axis = _chk_asarray(a, axis) log_a = ma.log(a) return ma.exp(log_a.mean(axis=axis)) |

Agreed. And as Ram Rachum hinted, there seems little point aiming to duplicate things that already exist in the de facto standard scientific libraries. So I think there's a place for a non-naive carefully computed geometric mean in the std. lib. statistics module, but I wouldn't see the point of simply adding an exp-mean-log implementation (not that anyone is advocating that). |

Thanks for the patch Steven! I won't comment about the code because I don't know enough about these algorithms, but I'm thinking, since you also did a refactoring of the statistics module, maybe these should be two separate patches/commits so it'll be easy to see which part is the new feature and which part is moving existing code around? |

Also... I like the detailed docstrings with the real-life examples! That stuff helps when coding and using an unfamiliar function (since I see the docs in a panel of my IDE), so I wish I'd see more detailed docstrings like these ones in the standard library. For `geometric_mean`, maybe I'd add one sentence that describes how the geometric mean is calculated. |

What no patch for pre-commit review?! For computing nth roots, it may be worth special-casing the case n=2: for floats, `math.sqrt` is likely to be faster and more precise than an ad-hoc algorithm. (Indeed, I'd expect it to be perfectly correctly rounded on the vast majority of current machines.) |

I thought about special-casing n=2 to math.sqrt, but as that's an implementation detail I can make that change at any time. According to my testing, math.pow(x, 0.5) is no worse than sqrt, so I'm not sure if there's any advantage to having yet another branch. I'd be interested in special-casing n=3 to math.cbrt (if and when it exists) now that its a standard C99 function. |

> According to my testing, math.pow(x, 0.5) is no worse than sqrt. It certainly is worse than sqrt, both in terms of speed and accuracy. Whether the difference is enough to make it worth special-casing is another question, of course, and as you say, that can happen later. |

As discussed with Ned by email, I'm currently unable to build 3.6 and won't have time to work on this before b1. As discussed on #27761 my tests here are too strict and should be loosened, e.g. from assertEqual to assertAlmostEqual. Ned wrote: "If you are only planning to make changes to the tests themselves, I think that can wait for b2." I have no plans to change the publicly visible interface of geometric_mean. |

Almost three years have passed. In the spirit of "perfect is the enemy of good", would it be reasonable to start with a simple, fast implementation using exp-mean-log? Then if someone wants to make it more accurate later, they can do so. In some quick tests, I don't see much of an accuracy loss. It looks to be plenty good enough to use as a starting point: --- Accuracy experiments --- >>> from decimal import Decimal >>> from functools import reduce >>> from operator import mul >>> from random import expovariate, triangular >>> from statistics import fmean >>> # https://www.wolframalpha.com/input/?i=geometric+mean+12,+17,+13,+5,+120,+7 >>> data = [12, 17, 13, 5, 120, 7] >>> print(reduce(mul, map(Decimal, data)) ** (Decimal(1) / len(data))) 14.94412420173971227234687688 >>> exp(fmean(map(log, map(fabs, data)))) 14.944124201739715 >>> data = [expovariate(50.0) for i in range(1_000)] >>> print(reduce(mul, map(Decimal, data)) ** (Decimal(1) / len(data))) 0.01140902688569587677205587938 >>> exp(fmean(map(log, map(fabs, data)))) 0.011409026885695879 >>> data = [triangular(2000.0, 3000.0, 2200.0) for i in range(10_000)] >>> print(reduce(mul, map(Decimal, data)) ** (Decimal(1) / len(data))) 2388.381301718524160840023868 >>> exp(fmean(map(log, map(fabs, data)))) 2388.3813017185225 >>> data = [lognormvariate(20.0, 3.0) for i in range(100_000)] >>> min(data), max(data) (2421.506538652375, 137887726484094.5) >>> print(reduce(mul, map(Decimal, data)) ** (Decimal(1) / len(data))) 484709306.8805352290183838500 >>> exp(fmean(map(log, map(fabs, data)))) 484709306.8805349 |
