A CmdStanDiagnose object is the object returned by the
$diagnose() method of a CmdStanModel object.
CmdStanDiagnose objects have the following associated
methods:
| Method | Description |
$gradients() | Return gradients from diagnostic mode. |
$lp() | Return the total log probability density (target). |
$init() | Return user-specified initial values. |
$metadata() | Return a list of metadata gathered from the CmdStan CSV files. |
$save_output_files() | Save output CSV files to a specified location. |
$save_data_file() | Save JSON data file to a specified location. |
