Description
Use linear min-max normalization or ln(value/minimum)/ln(maximum/minimum).
An index transforms inputs through a chosen scale, reference, or weighting scheme. Its denominator and normalization determine the meaning; a single term or unbounded score is not automatically a complete or officially defined index.
Use linear min-max normalization or ln(value/minimum)/ln(maximum/minimum).
When to use this tool
Use Development Index One Normalized Component when you need one explicit index term or normalization step.
How to use the tool and how it works
- Enter value, minimum, maximum, logarithmic. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read normalized. Use the output convention below.
Require maximum above minimum and, for logarithmic mode, positive minimum and value. Use linear min-max normalization or ln(value/minimum)/ln(maximum/minimum).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| value | Value under the stated unit, type, and placeholder convention. | Required. Finite number. |
| minimum | Minimum | Required. Finite number. |
| maximum | Maximum | Required. Finite number. |
| logarithmic | Logarithmic | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| normalized | Linear or logarithmic min/max score; not clamped to [0, 1]. | Required. Finite number. |

}Limitations and assumptions
- Results are not clamped and value may lie outside supplied bounds; no official index goalposts, indicator validity, or development ranking is selected.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Compute and review the full index using the intended methodology, including missingness and aggregation rules. Perform sensitivity analysis when reference choices or weights materially affect interpretation.
