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
