java.lang.Object
- org.datavec.api.transform.ops.AggregatorImpls.AggregableStdDev<T>

All Implemented Interfaces:

Serializable, IAggregableReduceOp<T,Writable>, Consumer<T>, Supplier<Writable>

Direct Known Subclasses:

AggregatorImpls.AggregableUncorrectedStdDev

Enclosing class:

AggregatorImpls
```
public static class AggregatorImpls.AggregableStdDev<T extends Number>
extends Object
implements IAggregableReduceOp<T,Writable>
```
This class offers an aggregable reduce operation for the unbiased standard deviation, i.e. the estimator of the square root of the arithmetic mean of squared differences to the mean, corrected with Bessel's correction. See https://en.wikipedia.org/wiki/Unbiased_estimation_of_standard_deviation This is computed with Welford's method for increased numerical stability & aggregability.
