Method Detail

avedev	back to summary
public static double avedev(double[] v) returns the mean of deviations from mean.

devsq	back to summary
public static double devsq(double[] v)

kthLargest	back to summary
public static double kthLargest(double[] v, int k) returns the kth largest element in the array. Duplicates are considered as distinct values. Hence, eg. for array {1,2,4,3,3} & k=2, returned value is 3. k <= 0 & k >= v.length and null or empty arrays will result in return value Double.NaN

kthSmallest	back to summary
public static double kthSmallest(double[] v, int k) returns the kth smallest element in the array. Duplicates are considered as distinct values. Hence, eg. for array {1,1,2,4,3,3} & k=2, returned value is 1. k <= 0 & k >= v.length or null array or empty array will result in return value Double.NaN

median	back to summary
public static double median(double[] v)

stdev	back to summary
public static double stdev(double[] v)

stdevp	back to summary
public static double stdevp(double[] v)

var	back to summary
public static double var(double[] v)

varp	back to summary
public static double varp(double[] v)
