Constructor Detail

DataSetIntArrays

public DataSetIntArrays(Meta metaobject)

Generic constructor method for the class

Parameters:

metaobject - A Meta class object containing metadata for the Stata dataset.

DataSetIntArrays

public DataSetIntArrays(Meta metaobject,
                        java.lang.Number missingValue)

Generic constructor method for the class

Parameters:

metaobject - A Meta class object containing metadata for the Stata dataset.

missingValue - A user defined value to use for representing missing values in the data

Method Detail

setFileName

public void setFileName()

Generic Setter method for the name of the dataset object

setData

public void setData()

Method to store Stata dataset as a 2d Array of Integer objects. This is used for passing the data set to objects/methods in the com.itemanalysis .psychometrics package to expand IRT modeling options in Stata.

Specified by:

setData in interface StataData

setData

public void setData(java.lang.Number missingValue)
