getIgnoreNaN

public boolean getIgnoreNaN()

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.

addResponseVariable

public void addResponseVariable(java.lang.String varname)

public void removeByVariable(java.lang.String varname)

Removes the variable as a "by-variable."

removeResponseVariable

public void removeResponseVariable(java.lang.String varname)

getN

public DataSet getN()

Return the normalizing observation number for each reported mean.

getResult

public DataSet getResult()

Return means.

run

public void run()

The mean over each unique combination of the "by-variables". A separate column is produced for each response variable and a separate row for each unique combination of the by-variables. While the by-variables may be numeric or categorical, the response variables must implement the
