Getting started

For most normal uses of blendz, the only class you should need is blendz.Photoz. This is designed to be the only user-facing class.

The order of things to do to use blendz is as follows:

• Setting the configuration - done either using configuration files or keyword arguments.
• Prior calibration - The prior parameters can be set manually in the configuration, or using the prior calibration procedure. The output of the default calibration procedure is another configuration file that can be read in, containing the prior parameters.
• Running the inference and model comparison - After running the nested sampling for each number of components under consideration, the posterior samples and blend probabilities are available for analysis.
