Having passed through a set of rigorous validation procedures, we were able to confirm the relevance between the questionnaire items and the latent variables previously established.
Both models were subject to rigorous validation procedures and the ultimate test being the use of test sets to determine the predictive power of the models.
The study also has clear strengths: We have subjected all data to rigorous validation procedures and have taken care to verify especially diagnostic and therapeutic information.
Rigorous validation procedures were used for the questionnaires to be employed here thus maximizing equivalency across all language groups on questions being asked.
The UML model enables a rigorous validation of several constraints.
Furthermore, a rigorous validation of the final model was performed by VPC against the external validation dataset.
This new data set has been analyzed with Back propagation ANNs employing a rigorous validation protocol.
Before using them, it is advisable to learn about their applicability and carry out a rigorous validation [ 22].
For a more rigorous validation, an exploratory factor analysis was performed starting from all questionnaire items that addressed newcomer integration.
All four approaches were tested using a rigorous inner/outer cross-validation procedure (Materials and Methods).
