*   Linear Fit
The process of determining a linear fit occurs as follows:
The Mass Frontier application applies Intensity = a + b (m/z) to a scan, and then applies the test for outlier data (using Student's t-distribution) to each scan peak.
In iterative form, the Mass Frontier application applies linear regression and exclusion of outlier peaks (signal) to each considered peak while finding no new outlier points.
The Mass Frontier application determines a threshold value as the intensity of the most intensive noise peak (the highest peak that is not excluded from noise).
