List of classAttribute() Examples

Examples of classAttribute()

weka.core.Instance.classAttribute()
Returns class attribute. @return the class attribute @throws UnassignedDatasetException if the class is not set or theinstance doesn't have access to a dataset
weka.core.Instances.classAttribute()
Returns the class attribute. @return the class attribute @throws UnassignedClassException if the class is not set

Examples of weka.core.Instance.classAttribute()
