--------------------------
Summary: Add mode function to StatUtils class
Key: MATH-1007
URL: https://issues.apache.org/jira/browse/MATH-1007
Project: Commons Math
Issue Type: New Feature
Reporter: Sebb
It might be useful to have a StatUtils function to get the mode.
However, this may be tricky as it does not easily fit in with the current
StatUtils design.
The mode can have multiple elements, but all the other methods only return a
single value.
There are at least two options for converting an array to a single value:
- arbitrarily (or randomly) pick one
- throw an Exception if there is more than one mode
Or maybe StatUtils should return a double array.
StatUtils also uses nested classes for all but the difference and normalize
methods. However the standard interfaces and classes don't support returning
arrays.
