Should OutlierPolicy maintain information on a Data Set #33

Closed DK96-OS closed 2 years ago

DK96-OS commented 2 years ago

Is this an important feature: for ensuring accuracy, improving efficiency, ease-of-use?

Should DeviationPolicy maintain an instance of DistributionCharacteristics? Originally posted by @DK96-OS in https://github.com/DK96-OS/MathTools/issues/32#issuecomment-1025694118

The policy could track whether the Data Set has been sorted.

If sorted, a much faster outlier algorithm could be used.

DK96-OS commented 2 years ago

When an outlier is removed, the DistributionCharacteristics might be able to be updated without summing up the list.

This idea can be implemented by some static function that uses:

Original List Size
Original DC
Value of Outlier removed

And produces a new DC.

The tricky part is handling precision.

The user would be able to access this function, but the big idea behind this Issue is how much should these details be managed by the library?
