Class of L2 differentiable parametric group families.

Objects can be created by calls of the form `new("L2ScaleFamily", ...)`

.
More frequently they are created via the generating function
`L2ScaleFamily`

.

`name`

[inherited from class

`"ProbFamily"`

] object of class`"character"`

: name of the family.`distribution`

[inherited from class

`"ProbFamily"`

[inherited from class

`"ProbFamily"`

: symmetry of`distribution`

.`param`

[inherited from class

`"ParamFamily"`

: parameter of the family.`fam.call`

[inherited from class

`"ParamFamily"`

] object of class`"call"`

: call by which parametric family was produced.`makeOKPar`

[inherited from class

`"ParamFamily"`

] object of class`"function"`

: has argument`param`

— the (total) parameter, returns valid parameter; used if`optim`

resp.`optimize`

— try to use “illegal” parameter values; then`makeOKPar`

makes a valid parameter value out of the illegal one.`startPar`

[inherited from class

`"ParamFamily"`

] object of class`"function"`

: has argument`x`

— the data, returns starting parameter for`optim`

resp.`optimize`

— a starting estimator in case parameter is multivariate or a search interval in case parameter is univariate.`modifyParam`

[inherited from class

`"ParamFamily"`

] object of class`"function"`

: mapping from the parameter space (represented by`"param"`

) to the distribution space (represented by`"distribution"`

).`props`

[inherited from class

`"L2ParamFamily"`

] object of class`"function"`

: mapping from the parameter space (argument`param`

of class`"ParamFamParameter"`

) to a mapping from observation`x`

to the value of the L2derivative;`L2deriv.fct`

is then used from observation`x`

to value of the L2derivative;`L2deriv.fct`

: mapping from the parameter space (argument`param`

of class`"ParamFamParameter"`

) to the set of positive semidefinite matrices;`FisherInfo.fct`

is used by`modifyModel`

to move the Fisher information according to a change in the parameter`FisherInfo`

[inherited from class
