The advantage of the curve fitting module is that it provides two modes of curve fitting: Calibration mode and Standard mode. In the Calibration Mode, an inverse prediction of X (abscissa) from Y (ordinate) is performed. As an example, if x is standard concentration values in mg/L and y is absorbance, then you can predict the concentration in mg/L from any absorbance value. The application derives X in linear and polynomials of the second and third degree by using equation roots.
The standard mode is available to fit datasets where high degree (up to 9th degree) polynomial fits are required or the Y needs to be predicted from X. Both modes provide the goodness of fit by calculating the correlation coefficient (r^2) and the relative percent difference (RPD) between the measured values and the predicted values.
The calculator is a scientific Reverse Polish Notation calculator and it can be also used to enter dataset points rapidly.
