Report

Declaration:

TRndForest.Report: TRFReport;

The readonly property Report returns various error and reliability measures of the model. The Report record contains the following charateristic parameters: RelClsError Training Set - Relative classification error (percent of incorrectly classified cases) AvgCE Training Set - Average cross-entropy (in bits per element) RMSError Training Set - root mean square error when estimating posterior probabilities AvgError Training Set - Average error when estimating posterior probabilities AvgRelError Training Set - Average relative error when estimating posterior probability of belonging to the correct class OOBRelClsError OOB Test - Relative classification error (percent of incorrectly classified cases) OOBAvgCE OOB Test - Average cross-entropy (in bits per element) OOBRMSError OOB Test - root mean square error when estimating posterior probabilities OOBAvgError OOB Test - Average error when estimating posterior probabilities OOBAvgRelError OOB Test - Average relative error when estimating posterior probability of belonging to the correct class

Hint:

Please note that due to compiler restrictions you cannot access the fields of the report property directly. Thus instead of directly accessing a report field, like err := RF.Report.OOBRMSError; you have to copy the report to an auxiliary variable and use this auxiliary variable to access the fields of the report: var auxrep : TRFReport; ... auxrep := RF.Report; err := auxrep.OOBRMSError; ...
