Why does null hypothesis testing matter for target validation in CAT-FAS?
Null hypothesis testing in CAT-FAS enables rigorous evaluation of whether observed functional changes exceed measurement noise, supporting confident target validation decisions in stroke therapeutic development.
How does independent variable isolation fit the discovery pipeline in CAT-FAS?
Isolating independent variables such as drug dose or genetic modification allows researchers to attribute functional changes measured by CAT-FAS to specific interventions, strengthening causal inference in early discovery.
What quantitative dependent variable measurements does CAT-FAS enable?
CAT-FAS generates T-scores, percentile ranks, and reliability metrics for upper extremity, lower extremity, postural control, and ADL functions, providing quantitative endpoints for therapeutic effect assessment.
Why do replication requirements matter for cross-functional collaboration in CAT-FAS?
Replication ensures that CAT-FAS-derived functional measurements are consistent across operators, sites, and studies, enabling reliable data sharing and collaborative decision-making in drug development programs.
What statistical analysis capabilities are required before implementing CAT-FAS?
Implementation requires proficiency in Rasch modeling, item response theory, and adaptive testing algorithms to ensure accurate score estimation and validity of the functional assessments.
