Generalized measurement error: Intrinsic and incidental measurement error.
1Measurement, Evaluation, and Research Methodology, University of British Columbia, Vancouver, British Columbia, Canada.
This study introduces two new types of measurement error (intrinsic and incidental) for random-valued data. It generalizes classical error models and statistical theories to this broader measurement domain.
Area of Science:
- Statistics
- Measurement Theory
- Data Science
Background:
- Traditional measurement error models apply to deterministic data.
- Handling random-variable-valued data requires new approaches to measurement error.
Purpose of the Study:
- To generalize measurement error concepts for random-variable-valued data.
- To introduce intrinsic and incidental measurement error.
- To extend classical statistical methods to this new data domain.
Main Methods:
- Formulation of intrinsic and incidental measurement error.
- Definition of calibrating conditions for generalized error models.
- Exploration of generalized point estimation, inference, and likelihood theory.
Main Results:
- Distinction between intrinsic and incidental measurement error.
- Generalization of classical measurement error models, including Berkson error.
- Adaptation of statistical inference for random-variable-valued measurements.
Conclusions:
- The proposed framework accommodates a broader range of measurement data.
- Generalized statistical theories provide tools for analyzing complex measurement processes.
- This work advances the understanding and modeling of measurement error in diverse applications.

Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
