1. **Outliers
Auto - **Progressive filter of outliers with termination at 99.9% correlation coefficient
or until only four data points remain, whichever happens first. This is accomplished in a
similar manner as the Manual filter.
Fig. 1 and Fig. 2 below illustrates this
option.

**Fig. 1** Plot
of the Wieland^{(1)} data using the
True Almen Saturation Curve Model. Excellent
correlation of 99.9% with a standard deviation of .048 (.000048in).

**Fig. 2** Data
from **Fig. 1** with multiple outliers introduced at
random points. Run 1 (orange) is the unfiltered plot - correlation is poor at
81.4% with a significant error of 1.381 (.001381in). Run 2 (green) is plot of
filtered data, terminated
at 99.9% correlation (identified outliers are flagged with asterisks). Calculated values are
comparable to those of **Fig. 1**.
