Method Detail

getConfidenceIntervalAt

double[] getConfidenceIntervalAt(double confidence)

Gets the confidence interval at given confidence level.

Parameters:

confidence - confidence level (e.g. 0.95)

Returns:

the interval in which mean lies with the given confidence level

getMeanErrorAt

double getMeanErrorAt(double confidence)

Gets the mean error at given confidence level.

Parameters:

confidence - confidence level (e.g. 0.95)

Returns:

the mean error with the given confidence level

isDifferent

boolean isDifferent(Statistics other,
                  double confidence)

Checks if this statistics statistically different from the given one with the given confidence level.

Parameters:

other - statistics to test against

confidence - confidence level (e.g. 0.95)

Returns:

true, if mean difference is statistically significant

compareTo

int compareTo(Statistics other)

Compares this statistics to another one. Follows the contract of Comparable.

Specified by:

compareTo in interface Comparable<Statistics>

Parameters:

other - statistics to compare against

Returns:

a negative integer, zero, or a positive integer as this statistics is less than, equal to, or greater than the specified statistics.

compareTo

int compareTo(Statistics other,
            double confidence)

Compares this statistics to another one. Follows the contract of Comparable.

Parameters:

other - statistics to compare against

confidence - confidence level (e.g. 0.99)

Returns:

a negative integer, zero, or a positive integer as this statistics is less than, equal to, or greater than the specified statistics.
