Class ParameterSet

The set of parameters used to fit theory to data.

ParameterSet forms a hierarchy of parameters. The parameters themselves are referred to by the path through the hierarchy, usually:

fitname.component.parameter

Though more or fewer levels are permitted. Parameters are assumed to have a unique label throughout the fit. This is required so that expressions tying the results of one fit to another can uniquely reference a parameter.

Attributes:

name: the name of the parameter set
path: the full dotted name of the parameter set
context: a dictionary providing additional context for evaluating parameters; Note that this namespace is shared with other theory functions, so populate it carefully.

Operations:

insert: add a new item to the set
append: add a new item to the end of the set
move: reorder the parameters in the set
