public class BasicStats
extends Object

The BasicStats class represents basic statistics about a certain numeric sequence. It was thought to compute basic statistic quantities, like mean and variance, iteratively for a flow of numeric quantities.

Method Summary

void	addValue(double xi) Adds a new double value to this statistics
void	addValue(int xi) Adds a new int value to this statistics.
double	getMax() Gives the maximum value added.
double	getMean() Gives the Mean value for this statistics.
double	getMin() Gives the minimum value added.
long	getNumValues() Gives the number of values computed for this statistics.
double	getStandDev() Gives the Standard Deviation for this statistics.
double	getVariance() Gives the Variance value for this statistics.
static void	main(String[] args) For testing/demonstration we use two samples of seven numbers which give rise to near the same mean but very different standard deviation.
void	print(String varname) Outputs the main statistic parameters.
