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. |
