Pmetrics validation object

Contains results of internal validation by simulation to permit generation of visual predictive checks (VPCs), prediction corrected visual predictive checks, (pcVPCs), normalized prediction distribution errors (NPDE), and numerical predictive checks.

Details

This object is created by running the make_valid method in a PM_result object. It contains all the information necessary to internally validate the result by simulation methods.
