Description Slots Objects from the Class Extends Note Author(s) References See Also Examples

Inverse hyperbolic sine transform class, which represents a transformation defined by the function:

*f(parameter,a,b)=sinh^{-1}(a*parameter)*b*

This definition is such that it can function as an inverse of
`sinht`

using the same definitions of the constants a
and b.

Object of class

`"transformation"`

– flow parameter to be transformed`transformationId`

Object of class

`"character"`

– unique ID to reference the transformation.

Objects can be created by calls to the
constructor `asinht(parameter,a,b,transformationId)`

Class `"singleParameterTransform"`

, directly.

Class `"transform"`

, by class "singleParameterTransform", distance 2.

Class `"transformation"`

, by class "singleParameterTransform", distance 3.

Class `"characterOrTransformation"`

, by class "singleParameterTransform", distance 4.

The inverse hyperbolic sin transformation object can be evaluated using the eval method by passing the data frame as an argument.The transformed parameters are returned as a matrix with a single column. (See example below)
