com.itemanalysis.psychometrics.data.VariableType

public class VariableType
extends java.lang.Object

The methods countDouble, countString, countMissing, getTotalCount, getValidCount, and isDouble are needed for importing data and management of the JTable. The JTable needs to know the class for a column data. Missing responses can cause a problem and possibly appear as a mix of Double and String. These methods are used to avoid this problem and determine whether a column is of class Double (i.e. isDouble) or String (i.e. not isDouble).
