Method Detail

addByVariable

public void addByVariable(java.lang.String varname)

Each unique combination of by-variables will result in a subset of data over which calculations will be performed.

removeByVariable

public void removeByVariable(java.lang.String varname)

Removes the variable as a "by-variable."

getResult

public DataSet getResult()

addPrimaryResponseVariable

public void addPrimaryResponseVariable(java.lang.String varname,
                              java.lang.String outvar)

Add a variable over which to perform the operation. If the ouput variable name names a column in which to output the results. This variable name may be the same as a variable already in the data set. In such a case the data already in the data set will be overwritten.

removePrimaryResponseVariable

public void removePrimaryResponseVariable(java.lang.String varname)

Removes the variable as a response variable.

addSecondaryResponseVariable

public void addSecondaryResponseVariable(java.lang.String varname,
                                java.lang.String outvar)

Add a variable over which to perform the operation. If the ouput variable name names a column in which to output the results. This variable name may be the same as a variable already in the data set. In such a case the data already in the data set will be overwritten.

removeSecondaryResponseVariable

public void removeSecondaryResponseVariable(java.lang.String varname)

Removes the variable as a response variable.

run

public void run()
