There is a direct relationship between instrument reliability and sensitivity to change as instruments that are prone to higher variability between assessments may not detect significant longitudinal change as accurately as instruments with lower between-assessment variability.
Knopman and Caselli [ 34] point out that between-assessment variability is an inherent challenge when using patient-based objective cognitive tests to assess change, and longitudinal differences may be related to non-pathological factors, such as chance and regression toward the mean.
Across assessment periods variability seemed to increase in each trial (A1 through B2) for reached target.
The prerequisite for practical implementation is the assessment of variability in soil texture, water and nutrients distribution, and pest infection.
These comprehensive measurements allowed for the detailed assessment of variability in leaf pollen deposition in detail for each site over time.
They included local evaluation on training and test signals, calculation of global void fraction values, and an assessment of variability among different experts.
The interpretation of changes in the intensity and size of metastatic lesions on bone scans can be a difficult task and to some extent a subjective assessment causing variability between different readers.
On each carrier, the array was spotted twice to allow assessment of variability in substrate phosphorylation.
The framework enables visualization and structural assessment of variability.
