Health Index Calculator
Linear health-index normalization with independently applicable edition goalposts and life-expectancy estimate; outside-goalpost values stay signed/unclipped, not diagnosis or verified published HDI.
Description
A normalized health index locates life expectancy between adopted goalposts.
A normalized health index locates life expectancy between adopted goalposts.1
The reference edition and population definition determine those supplied bounds.
When to use Health Index Calculator
Use this tool to obtain conditionalHealthIndex from the supplied records using the stated calculation. Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
How to use Health Index Calculator and understand its results
- Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
- Enter observedLifeExpectancyYears, callerApplicableMinimumYears, callerApplicableMaximumYears, using the field meanings and rules below, then run the tool.
- Read result.conditionalHealthIndex. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedLifeExpectancyYears | Observed life expectancy years | number | Required |
| callerApplicableMinimumYears | Caller applicable minimum years | number | Required |
| callerApplicableMaximumYears | Caller applicable maximum years | number | Required |
Require nonnegative observed life expectancy and finite minimum/maximum goalposts with maximum>minimum. The goalposts themselves are not required to be nonnegative. Normalize linearly without clamping; results outside [0,1] are accepted.
healthIndex=(lifeExpectancy−minimum)/(maximum−minimum) Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.conditionalHealthIndex | Linear position of life expectancy between caller-established goalposts; no clamping. | number |

}Limitations and assumptions
Population definitions, survey design, calibration and observation coverage are independently established. A result describes the supplied record or conditional model without demonstrating causation, validating an instrument or supplying representative population evidence.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
