When does one accept that a model has been mis-specifed and how can this be corrected?

12 January 2018 1 8K Report

The model in question is a linear one.

When does one accept that a model has been miss-specified and how can this be corrected?

A research model may have flaw in the following aspects (not exhaustive list):

the research model is not underpinning on the previous theories / theoretical frameworks etc. after rigorous literature review.

the research model underpinning on the outdated previous theories / theoretical frameworks etc. which have been falsified but unknown to the researchers.

underpinning on reasonable correct previous theoretical frameworks etc. but operationalized with wrong / flawed operational definitions or research instruments / survey questionnaires.

due to lack of literature review / artifacts on certain very new area of research, the researcher borrow the irrelevant or wrong theories / theoretical frameworks.

From my personal experience, in order to correct the above model miss-specification, followings can be taken (not exhaustive list):

the researcher himself / herself perform further rigorous literature review until saturation.

seek other people to review & comment e.g. colleagues, peers, senior researchers, thesis supervisor etc.

present your research proposal / conceptual framework / research model during colloquiums / research conference etc. so that audience can comment - finding this way can also help the researcher to learn a lot from others or in different perspectives.
