Plot the Posterior PDFs

You can examine the posterior probability density functions to get a quantitative look at the results of the model fitting process using :func:`visualize.posteriorPDF`:

import visualize
visualize.posteriorPDF()

This will produce a series of histograms showing the posterior probability distribution functions for every parameter in the model.

This routine also prints the average and 1-sigma rms uncertainty on each parameter of the model.

You can also see how the posterior PDF of every parameter in the model changes as a function of iteration using :func:`visualize.evolvePDF`:

visualize.evolvePDF()

This function essentially produces a posteriorPDF every stepsize iterations. The default is stepsize = 50000. You can then view the evolution in the PDF using a viewer application like Preview.
