| LinearTransformation | The representation of a linear transformation between real numbers xandy. | 
| LinearTransformation.LinearTransformationBuilder | This is an intermediate stage in the construction process. | 
| PairedStats | An immutable value object capturing some basic statistics about a collection of paired double
 values (e.g. | 
| Quantiles.Scale | Describes the point in a fluent API chain where only the scale (i.e. | 
| Quantiles.ScaleAndIndex | Describes the point in a fluent API chain where the scale and a single quantile index (i.e. | 
| Quantiles.ScaleAndIndexes | Describes the point in a fluent API chain where the scale and a multiple quantile indexes (i.e. | 
| Stats | A bundle of statistical summary values -- sum, count, mean/average, min and max, and several
 forms of variance -- that were computed from a single set of zero or more floating-point values. | 
| StatsAccumulator | A mutable object which accumulates double values and tracks some basic statistics over all the
 values added so far. |
