Zachary Tong 8af0e7c4b6 Only create final MatrixStatsResults on final reduction (#39205) ... MatrixStatsResults is the "final" result object, and runs an additional computation in it's ctor to calculate covariance, etc. This means it should only run on the final reduction instead of on every reduce.		2019-02-21 14:18:45 -05:00
