Activities

Intentions

There have been many statistical advances to address measurement error in the past few decades. With our activities we intend to raise the awareness for the topic and to overcome barriers to using measurement error adjustment methods, e.g.

  • Lack of, or problems with data for determining the measurement error model and estimating its parameters

  • Inadequate standards of "validation" of measurement instruments

  • Lack of appreciation of the biases and the loss of precision resulting from measurement error

  • Lack of software for implementing methods of adjustment

General relevance

Article on the general problem of measurement error in epidemiology intended for the intelligent layman

Literature survey

Literature survey about current practice for addressing measurement error in four areas of epidemiology in which measurement error is known to be extensive

Guidance

Main document on guidance on dealing with measurement error and misclassification intended for biostatisticians

Further projects

Projects that are currently ongoing include the construction and use of prediction equations, handling error-prone continuous variables that have been categorized, a case study on how to do measurement error correction in practice and error in measurements of dietary intake used in nutritional epidemiology.
