public class WekaInstancesStatistic
extends AbstractTransformer

Generates statistics from a weka.core.Instances object.
The actor just uses the internal format (double array) and does not check whether the attributes are actually numeric.

Input/output:
- accepts:
weka.core.Instances
- generates:
adams.core.io.SpreadSheet

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: InstancesStatistic
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-type <ROW_BY_INDEX|COLUMN_BY_INDEX|COLUMN_BY_REGEXP> (property: dataType)
    Whether to retrieve rows or columns from the Instances object.
    default: COLUMN_BY_INDEX
 

-location <adams.core.base.BaseString> [-location ...] (property: locations)
    The locations of the data, depending on the chosen data type that can be
    either indices or regular expressions on the attribute names.
    default:
 

-statistic <adams.data.statistics.AbstractArrayStatistic [options]> (property: statistic)
    The statistic to generate from the data.
    default: adams.data.statistics.ArrayMean
