This "how to" describes the process to implement a bias/slope correction for an index. Examples and 3 methods for correcting the equations are presented.
HunterLab has introduced in its Vista product via EasyMatch Essentials software, a measurement correction algorithm that allows the user to adjust the instrument’s base performance via a Bias and Gain correction to precisely match reported results to assigned values for physical standards.
The Y(adjusted Index value)=m(gain)*uncorrected Index Value + offset (bias) equation allows the end user to correct reported values using standard sets numbering just one value to many.
