Analyzing MCMC Calculations¶
Point: triangle plots, recovered quantities, etc.
If you don’t yet have a dataset to work with, you can make one by following the
To begin, initialize an instance of the analysis class, ModelSet
:
anl = ares.analysis.ModelSet('test_model_grid')
First, let’s verify that we’ve surveyed the part of parameter space we intended to:
ax = anl.Scatter('fX', 'fstar')
You should see a scatterplot with points in the \(f_X\)—\(f_{\ast}\) plane representing the models in our grid.
Basic Inspection¶
Now, the kind of analysis you can do will be limited by what quantities
were saved for each model. Recall (from example_grid_I
) that we have
the following quantities at our disposal:
