List of valueSparse() Examples

Examples of valueSparse()

weka.core.Instance.valueSparse()
Returns an instance's attribute value in internal format. Does exactly the same thing as value() if applied to an Instance. @param indexOfIndex the index of the attribute's index @return the specified value as a double (If the correspondingattribute is nominal (or a string) then it returns the value's index as a double).
