class StructureEngine( Engine )	[source]

The StructureEngine varies the internal structure of the model.

Only for Models that are Modifiable.

The member is kept when the logLikelihood > lowLhood.

Attributes
None of its own

Attributes from Engine
walkers, errdis, slow, maxtrials, rng, report, phantoms, verbose

Author Do Kester.

StructureEngine( walkers, errdis, copy=None, **kwargs )	[source]

Constructor.

Parameters

• walkers : list of Walker
       walkers to be diffused
• errdis : ErrorDistribution
       error distribution to be used
• copy : StructureEngine
       to be copied
• kwargs : for Engine
       "phantoms", "slow", "seed", "verbose"

copy( )	[source]

execute( kw, lowLhood, iteration=0 )	[source]

Execute the engine by changing a component.

Parameters

• kw : int
       index of walker to diffuse
• lowLhood : float
       lower limit in logLikelihood
• append : bool
       set walker in place or append in walkerlist
• iteration : int
       iteration number

Returns

• int : the number of successfull moves

executeOnce( wlkrid, lowLhood, location=None )	[source]

One execution call.
