Usually developed and validated on one registry only using a split-data approach, their validity when subjected to external validation has only been assessed to a limited extent.
A major advantage of using Kane's (2006) argument-based approach to validity is that it "provides a relatively pragmatic approach to validation" (Kane 2012, p. 15).
"In any market research approach, the validity of insights is derived not just by listening to what customers say, but the ability to interpret findings and uncover the underlying insights.
In the work presented, we investigate a model system to illustrate the approach's validity.
Today, Delphi studies are more valid than in the beginning of Delphi studies in 1960s because of a more critical approach to validity questions.
Turbulence/chemistry interaction is modeled with a laminar flamelet library approach, the validity of which is demonstrated in the present work.
The time-domain indicial approach, whose validity has been only partially investigated in the past, is selected for the modeling of self-excited forces.
The contents herein are based on conveniently performable lab-scale diametrical compression measurements on model microcrystalline cellulose pellets demonstrating feasibility of the approach and validity of the contribution.
