만약 그렇다면 어떻게 할까?
1. Adjust your scale so that you add 1 to every number in the data set, and then subtract 1 from the resulting geometric mean.
2. Ignore zeros or missing data in your calculations.
3. Convert zeros to a very small number (often called “below the detection limit”) that is less than the next smallest number in the data set.
