Due to using a clearly defined and proven measurement protocol, abnormalities were mainly caused by transcription errors and could be identified in the plotting step.
By contrast, traditional EFA has limitations with respect to comparing equivalence of factor structures and, thus, proving measurement invariance across multiple groups.
At the department of epidemiology and biostatistics, University Medical Center, Amsterdam, NL, a group recently established guidelines to assess and prove measurement properties and qualities of self-assessed health outcome instruments [ 1, 2].
Once again, the proposed linear model was proved by measurements (see Figures 7 and 8).
As plotted in Figure 3, a strong linear correlation was proved between measurements obtained from quantitative RT PCR and microarray analyses (R=0.99; P<0.0001).
As it was proved by measurements undertaken until week 27, specific antibody titers were in all cases over 1 640, persisted in time and, as it was expected, notably increased after revaccination at week 24.
Results of experiments, proving the measurement quality of the whole device are presented as well.
Before next processing, the size of tested images was reduced in size to 685 × 584 pixels and calibrated to prove the measurement of pathological changes comparable.
These results prove that measurement of the ATP level is a reliable means of assessing both the viability and metabolic capacity of liver slice cells.
