1. The slope of the line, m : 2. The intercept, b : 3. The standard deviation about regression, sr : 4. The standard deviation of the slope, sm : 5. The standard deviation of the intercept, sb : 6. The standard deviation for results obtained from the calibration curve, sc :
4-8 Calibration Curves
8D-2 Linear Dynamic Range ⇒ upper limit: 직선성으로 부터 5%의 deviation이 시작되는 곳 ⇒ 선형이 단순하고, 비이상적인 신호 검출이 용이하기 때문에 유리 함 → 비선형이 사용될 수도 있음 ⇒ 선형 측정범위가 큰 것이 좋음
