Method Detail

set

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

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

increment

void increment(int k,
               int cond)

Increments the observed count of k conditioned on cond.

increment

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

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

get

int get(int k,
        int cond)

Returns the observed count of k conditioned on cond.

getMarginalCount

long getMarginalCount(int k)

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

getConditionalDistribution

Int2IntFrequencyDistribution getConditionalDistribution(int 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.
