The emphasis for developing a statistical model is to test the validity of the hypothesis represented by the model.
The convergent and divergent validity of the factors represented in the CLEQ was investigated by calculating Pearsons Product Moment correlations between them, therewith testing our hypotheses.
Second, for those who adopted the CFA approach, the MetS is usually accepted as the underlying framework in their analysis; we did not want to do that, but rather question the validity of the present MetS to represent an integrated pathophysiological phenomenon.
These homoplasious events are presumably mainly due to recombination (significant in all four separate tests, P = 0.02, P = 0.001, P < 0.001, P < 0.001; see Table 1), which negates the validity of representing the Ci genealogy as a strictly bifurcating tree as in the likelihood analysis (Fig. 4).
However, concerns have been expressed about its reliability, regarding the neglect of primary creep (after a very short initial transient) and about the validity of representing the stress and strain rate via these "equivalent" values.
Finally, the validity of the new model represented by porosity and (r35) was tested using 123 rock samples (sandstone and limestone).
The optimal outcome in terms of validity of the model is represented by the absence of statistically significance differences among the distributions, meaning that a subsample of data produced by the model is not different from the empirical data.
The validity of a questionnaire represents the degree to which it measures what it is meant to measure.
Recent evidence suggests that the different scoring approaches will affect the validity of the summary scores, as represented by the RAND-12 and SF-12 [ 29, 30].
Qualitatively agreement between predictions and numerical results confirms the validity of the simplified model to represent the behavior of the original equations.
