Coefficient of Determination (R²) Calculation & Interpretation
WebStep 1: Examine the fitted regression line to assess linearity. Linearity assesses the difference in average bias through the expected operating range of the measurement system. Use the Bias versus Reference Value plot to see how the bias values vary for each part. For each reference value, the blue circles represent the bias values, and the ... WebHochschule Bremen.
