Geometric Mean Return (Definition, Formula) How to Calculate?
WebTo calculate a geometric mean by hand: Transform all the values to their logarithms. Compute the mean of the logaritms. Compute the antilog of the mean. It doesn't matter what logarithm base you use, so long as you are consistent. If the logarithms in step 1 are common (base 10) logs, then the geometric mean in step 3 is computed by taking 10 ...

Geometric Mean Return (Definition, Formula) How to Calculate?
WebThe calculation of the Geometric Mean may appear impossible if one or more of the data points is zero (0). In these cases, however, the convention used is that a value of either '1', one half the limit of detection, or some other substitution is allowed for each zero or "less than" value, so that the information contained in these data is not lost. WebApr 10, 2024 at 14:50. @Jordan The reason nan s are being returned is not because of the 0s, but because of the negative values. This is how geometric mean works: .02 * -.001 * .05 * .43 = -4.3000000000000007e-07 -4.3000000000000007e-07 ** (1/ 4) = nan This has nothing to do with 0s in the formula, and everything to do with the fact that ...
