getSampleRateOfTheSpace

public static int getSampleRateOfTheSpace(java.util.ArrayList<java.lang.Double> theSpace,
                                          int stepSizeOfTheBurnIn)

Looks either for major decline in theSpace or if we get very close to the average line. Then we break.

Parameters:

theSpace - Gives you the average similarity between samples that have index * stepSizeOfTheBurnIn steps between them (theSpace[2] gives you the average similarity between samples that are 2 * stepSizeOfTheBurnIn steps away)

stepSizeOfTheBurnIn - only used in the end, maybe unnecessary ?

Returns:

the desired sampling rate (int)

shouldStopSampling

public static boolean shouldStopSampling(java.util.ArrayList<java.lang.Double> distances)

If the last element in the distances variable is larger than PERCENT_CONST we stop.

Parameters:

distances - ArrayList of distances between consecutive fuzzyAlignments

Returns:

True if we want to stop, else false

shouldStopBurnIn

public static boolean shouldStopBurnIn(java.util.ArrayList<java.lang.Double> logLikeList)

If the logLikelihood has a major decline, we stop the burnin

Parameters:

logLikeList - List of the values where we look for the decline

Returns:

true if we found a major decline in the logLikeList and we want to stop sampling, else false
