Definitions:
R-Squared
A statistical measure that represents the proportion of the variance for a dependent variable that's explained by an independent variable or variables in a regression model.
F-Ratio
A statistical measure used in the analysis of variance (ANOVA) to compare the variability between groups with the variability within groups.
Diagnostic Display
High-quality, specialized monitors used in medical imaging to ensure accurate and precise viewing of digital medical images for diagnostic purposes by healthcare professionals.
Studentized Residuals
