Field Detail

_rfModelKey

protected final Key _rfModelKey

_domain

protected final java.lang.String[] _domain

_errorsPerTree

protected final long[] _errorsPerTree

_computedOOB

protected final boolean _computedOOB

_valid

protected boolean _valid

_matrix

protected long[][] _matrix

The Confusion Matrix - a NxN matrix of [actual] -vs- [predicted] classes, referenced as _matrix[actual][predicted]. Each row in the dataset is voted on by all trees, and the majority vote is the predicted class for the row. Each row thus gets 1 entry in the matrix.

_errors

protected long _errors

Number of mistaken assignments.

_rows

protected long _rows

Number of rows used for building the matrix.

_skippedRows

protected long _skippedRows

Number of skipped rows. Rows can contain bad data, or can be skipped by selecting only out-of-back rows
