Problem Note 50171: Start Groups node Bagging Percentage property values used are not correct
The Start Groups node in SAS® Enterprise Miner™ enables you to specify a Percentage property for Bagging. Use the Percentage property to specify the sample size as a proportion of the input data set observations. However, the node might not use the percentage value that you specify. Regardless of the Bagging Percentage property value that you specify, the actual percentage that is used fluctuates around an average of about 62% in repeated tests.
There are no errors or warnings.
There is no workaround.
