How to use it in your own spreadsheet
- Identify the cells or inputs that correspond to the sample values above.
- Enter the formula in an empty cell, changing the references or literal values to match your sheet.
- Compare the output with a manual check on a small known example.
- Extend the formula to a larger dataset only after you understand the result.
Common problems and practical checks
- Confirm that the data represents the intended sample, population, rate or cash-flow timing.
