Constructor Detail

ListUnivariateImpl

public ListUnivariateImpl()

No argument Constructor

ListUnivariateImpl

public ListUnivariateImpl(java.util.List list)

Construct a ListUnivariate with a specific List.

Parameters:

list - The list that will back this DescriptiveStatistics

ListUnivariateImpl

public ListUnivariateImpl(java.util.List list,
                          org.apache.commons.math.util.NumberTransformer transformer)

Construct a ListUnivariate with a specific List.

Parameters:

Returns:

the computed value of the statistic.

getTransformer

public org.apache.commons.math.util.NumberTransformer getTransformer()

Access the number transformer.

Returns:

the number transformer.

setTransformer
