names - External interface¶

Exported names.

In model definition scripts, rather than importing symbols one by one, you can simply perform:

from bumps.names import *

This is bad style for library and applications but convenient for model scripts.

The following symbols are defined:

• np for the numpy array package
• sys for the python sys module
• inf for infinity
• pmath for parameter expressions like 2*pmath.sin(M.theta)
• Parameter for defining parameters
• FreeVariables for defining shared parameters
• Distribution for indicating prior probability for a model parameter
• Curve for defining models from functions
• PoissonCurve for modelling data with Poisson uncertainty
• PDF for fitting a probability distribution directly
• FitProblem for defining the fit (see BaseFitProblem or MultiFitProblem for details, depending on whether you are fitting a single model or multiple models simultaneously).
