Propagates uncertainty
Option | Description |
---|---|
Inherent capacity | Fully incorporates input and parameter uncertainty into output intervals. |
Model-specific tools | Specialized extensions or package functions (e.g., bootstrap routines, sandwich variance estimators, delta method) are available to propagate uncertainty for that method. |
Needs model-agnostic propagation | Requires external, generic workflows (e.g., Monte Carlo simulation, bootstrap wrappers) to track and quantify uncertainty across model outputs. |
Definition
The method’s built-in ability to carry the quantified uncertainty of inputs (e.g., measurement error, parameter estimation variance) through the analysis to produce valid confidence or credible intervals on outputs.
Explanation
Proper uncertainty propagation prevents overconfident conclusions by ensuring that input errors and model uncertainties are reflected in the final inference. Some methods do this inherently; others require external tools or custom workflows. Methods lacking this aspect provide point estimates without a realistic appraisal of their reliability.
Tools/rationale for helping assessment
- Decide if you require your RS measurement error (e.g. ±σ per pixel) to flow into your final effect estimates.
- If you need full integration with no extra coding, choose
Inherent capacity
; if availability via method‐specific additional routines suits you (e.g. bootstrap), chooseModel-specific tools
; if you plan a separate Monte Carlo wrapper, chooseNeeds model-agnostic propagation
.
Example
Your LiDAR canopy‐height σ is 0.3 m/pixel and you want those errors to propagate in your biomass estimate’s CI: i) with no time-consuming coding efforts: you pick Inherent capacity
; ii) you are ok with some additional dedicated function calls and parameter tweaking: Model-specific tools
