Phosphine Detection Significance Sigma Level Classifier
Actual fitted phosphine-feature signed signal/error relative to caller statistical threshold. Does not address look-elsewhere effects, non-Gaussian/systematic noise, line identity, abundance or life; no universal detection class.
Description
A fitted feature's sigma ratio divides amplitude by an independently established error.
A fitted feature's sigma ratio divides amplitude by an independently established error.1
Statistical significance alone does not establish molecular identification or biological origin. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Phosphine Detection Significance Sigma Level Classifier
Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the observation or experimental context, reference/calibration source, unit basis and adopted model assumptions.
How to use Phosphine Detection Significance Sigma Level Classifier and understand its results
- Establish the observation or experimental context, reference/calibration source, unit basis and adopted model assumptions.
- Enter independentlyFittedFeatureAmplitude, independentlyEstablishedOneSigmaError, callerRequiredAbsoluteSigma, using the field meanings and rules below, then run the tool.
- Read result.conditionalSignedSigma, result.meetsCallerAbsoluteThreshold. Interpret each field using the units, signs and evidence rules below.
- If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyFittedFeatureAmplitude | Independently fitted feature amplitude | number | Required |
| independentlyEstablishedOneSigmaError | Independently established one sigma error | number | Required |
| callerRequiredAbsoluteSigma | Caller required absolute sigma | number | Required |
Require finite signed fitted amplitude, positive one-sigma error and positive required absolute sigma. Return amplitude/error and flag abs(ratio)≥threshold, including equality. Negative features retain their sign; the tool does not estimate error or identify phosphine.
signedSigma=featureAmplitude/oneSigmaError; meets=(abs(signedSigma)≥callerThreshold) Apply the field units and exact ordering, boundary and evidence rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result containing the calculation or selected reference fields below | object |
| result.conditionalSignedSigma | Conditional Signed Sigma; use the units, sign convention and calculation stated above | number |
| result.meetsCallerAbsoluteThreshold | Meets Caller Absolute Threshold; use the units, sign convention and calculation stated above | boolean |

}Limitations and assumptions
Statistical significance alone does not establish molecular identification or biological origin. Results depend on the independently established measurement basis and the exact model assumptions above.
Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
