Sub Sample Options
Sub sampling is useful for large data sets, as often all of the data is not required for the fit and a subset allows the computation to perform much more quickly.
Relationships provide sub-sampling controls to increase processing speed for large data sets. These include two categories:
Fit using every i-th point
Using the Fit using every i-th point control provides the ability to display a reduced number of vectors that continues to increase in number as the data set increases in size. When i=1, all the point deviations are used for display and calculation. As i increases so does the number of skipped points.
Fit using no more than n points
Using the Fit using no more than n points control provides the ability to place a hard limit on the number of points used in the relationship for display and reporting purposes.
