Hi @lj17525194100

Thanks for your feedback!

(1) mTrain parameter
mTrain is the number of samples, which are selected as the training set.

(2) outF parameter
outF parameter is the anomaly scores of samples calculated by AnomalyScore function in IsolationForest package.
You can calculate it using this script:

The definition of AnomalyScore function is as following:
