Subject [jira] Created: (MATH-219) removeData methods for SimpleRegression
Date Tue, 19 Aug 2008 04:41:44 GMT
removeData methods for SimpleRegression

                 Key: MATH-219
             Project: Commons Math
          Issue Type: New Feature
            Reporter: Andrew Berry
            Priority: Trivial

I've implemented removeData methods for the org.apache.commons.math.stat.regression.SimpleRegression
class. They mirror the existing addData methods. My reason for adding them is to support regression
calculations across a sliding window of (time-based) observations without having to recalculate
for the entire window every time.

I'll attach patch files for the class and its junit test class. I'm not too concerned if these
are added to the commons math library (I have made a copy in my own class hierarchy) but thought
other might find this useful.
