1. Are instances of org.apache.commons.math.stat.descriptive.DescriptiveStatisticsImpl thread-safe?
No, they are not. Version 2.0 includes synchronized versions of several classes, including a SynchronizedDescriptiveStatistics class.
2. Can code derived from "Numerical Recipes" routines be included in commons-math?
Algorithms implemented in "Numerical Recipes" are licensed under terms that are incompatible with the Apache license. As such, commons-math can not contain any code derived from these routines. The precedent we have established is to not allow any code developed using NR as a source and instead find alternate citations for the algorithms detailed in NR.
