I am "consistently" getting java.lang.OutOfMemoryError while trying
to use DescriptiveStatistics.
The files I am using are relatively large and I need to analyze the
byte distributions in them. I am taking care of clearing the cash each
time I run a new sample . . .
I can't quite get why this is happening, when all you need are at the
most 6 double variables which values you would incrementally update
based on well-known formulas.
Why would such OutOfMemoryError happen?
Is there a way around that problem?
