Interface Object2IntConditionalFrequencyDistribution<K extends Comparable<K>>

All Known Implementing Classes:

Object2IntConditionalFrequencyDistributionEntry

public interface Object2IntConditionalFrequencyDistribution<K extends Comparable<K>>

A conditional frequency distribution where events are arbitrary objects and counts are ints.

Method Summary

void	check() Performs an internal consistency check of this data structure.
int	get(K k, K cond) Returns the observed count of k conditioned on cond.
Object2IntFrequencyDistribution<K>	getConditionalDistribution(K cond) Returns the frequency distribution conditioned on cond.
long	getMarginalCount(K k) Returns the marginal count of k.
long	getSumOfAllCounts() Returns the sum of all counts.
void	increment(K k, K cond) Increments the observed count of k conditioned on cond.
void	increment(K k, K cond, int v) Increments the observed count of k conditioned on cond by v.
void	set(K k, K cond, int v) Sets the observed count of k conditioned on cond to v.

Method Detail

set

void set(K k,
         K cond,
         int v)

Sets the observed count of k conditioned on cond to v.

increment

void increment(K k,
               K cond)

Increments the observed count of k conditioned on cond.

increment

void increment(K k,
               K cond,
               int v)

Increments the observed count of k conditioned on cond by v.

get

int get(K k,
        K cond)

Returns the observed count of k conditioned on cond.

getMarginalCount

long getMarginalCount(K k)

Returns the marginal count of k. That is, sum of counts of k conditioned on all cond.

getConditionalDistribution

Object2IntFrequencyDistribution<K> getConditionalDistribution(K cond)

Returns the frequency distribution conditioned on cond.

getSumOfAllCounts

long getSumOfAllCounts()

Returns the sum of all counts.

check

void check()

Performs an internal consistency check of this data structure. An exception will be thrown if an error is found.
