- Running a test when there are no observations of at least one of the sets now breaks the MWU contract
+ MWU returns Pair(Double.NaN,Double.NaN) in these instances to maintain the contract of never returning null
+ No more Double.Infinity values will appear
- RankSumTests now probe the return values for NaNs, and don't annotate if they appear
- For small sets where the probability is calculated recursively, the z-value is now the inversion of the error function
and not the approximate z-value
- UG and Annotator integration tests updated to reflect changes

- Comment fixes to better explain why two-sided test wants to use the LOWER (not higher) value for U
- Much more direct testing of MWU functions
- Uniform approximation was always using the < cumulant (sometimes the > cumulant should be used instead)
- Uniform approximation currently not used (regime in which it was being used was not the right one -- not necessarily bad, but not an improvement over normal)
+ this particular approximation is for major imbalances of the form m >> n. Code may be altered in the future to use this method for this particular regime, if the method's not too slow.
- Hook into one-sided test.
RegionalAssociationRecalibrator: NaNs were being caused by presence of Infinity and -Infinity values out of the walker. Currently I'm just re-setting them to arbitrary post-whitened values, but the walker will be changed to prevent output of these values, and the "fix" will undone.

- RefMetaDataTracker: grabbing variant contexts given a prefix (not sure where else this was implemented, if someone can show me I'll remove it)
- VCFUtils: grabbing VCF headers given a prefix
- MathUtils: Useful functions for calculating statistics on collections of Numbers
- VariantAnnotator: Made isUniqueHeaderLine a public static method -- maybe this should go into a different class. Not sure.
- Associations: PluginManager now used to propagate classes, implementations for Z,T,U tests, slight alteration to format to make the objects stored
in the window optionally different from those returned by whatever statistic is run across the window
Added:
- MannWhitneyU. Started to fix up WilcoxonRankSum but there are comments in there questioning the validity of some of the code, and I'm sure that
it's actually doing a U test. This implementation includes the direct calculation of p-values for small sample sizes, and a uniform approximation
for when one of the sample sets is small, and the other large. Unit tests to follow.
- BootstrapCallsMerger: takes n VCFs which have been called on the same samples; merges them together while averaging the annotations
- BootstrapCalls.q: qscript for testing the effectiveness of boostrap low-pass calling on the exome
