Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`T`	`constant(double value)`	Generate a constant `Derivative`.
`default Field<T>`	`getField()`	Get the `Field` to which the generated derivatives belongs.
`List<ParameterDriver>`	`getSelected()`	Get the parameters selected for estimation.
`T`	`variable(ParameterDriver driver)`	Generate a `Derivative` representing the parameter driver either as a canonical variable or a constant.

- Method Detail
  - getSelected
```
List<ParameterDriver> getSelected()
```
    Get the parameters selected for estimation.
    
    Returns:
    
    parameters selected for estimation
  - constant
```
T constant(double value)
```
    Generate a constant Derivative.
    
    Parameters:
    
    value - value of the constant
    
    Returns:
    
    constant Derivative
  - variable
```
T variable(ParameterDriver driver)
```
    Generate a Derivative representing the parameter driver either as a canonical variable or a constant.
    The instance created is a variable only if the parameter has been selected for estimation, otherwise it is a constant.
    
    Parameters:
    
    driver - driver for the variable
    
    Returns:
    
    variable Derivative
  - getField
```
default Field<T> getField()
```
    Get the Field to which the generated derivatives belongs.
    
    Returns:
    
    Field to which the generated derivatives belongs
