Enum Constant Summary
Enum Constants Enum Constant Description EXCLUSIVE
Excludes end points.INCLUSIVE
Includes end points.MEDIAN
Percentile of i-th point is (i-1/3)/(n+1/3) * 100%.MID
Mid range, Percentile of i-th point is (i-0.5)/n * 100% so highest and lowest points correspond to (1-0.5)/n-th and (n-.5)/n-th percentiles.NEAREST
Nearest rank, smallest value such that least p% of the data is less than or equal to that value.

NEAREST
public static final Percentile.Type NEAREST
Nearest rank, smallest value such that least p% of the data is less than or equal to that value.
-
INCLUSIVE
public static final Percentile.Type INCLUSIVE
Includes end points. The percentile of i-th point is (i-1)/(n-1)*100% so the lowest and highest values corresponds to 0-th and 100-th percentiles. Like EXCEL's Percentile method
-
EXCLUSIVE
public static final Percentile.Type EXCLUSIVE
Excludes end points. Percentile of i-th point is i/(n+1)*100% so lowest and highest values correspond to 1/(n+1)-th and n/(n+1) percentiles. Like EXCEL's Percentile.EXC method
-
MID
public static final Percentile.Type MID
Mid range, Percentile of i-th point is (i-0.5)/n * 100% so highest and lowest points correspond to (1-0.5)/n-th and (n-.5)/n-th percentiles. Like Matlab's prctile method.
-
MEDIAN
public static final Percentile.Type MEDIAN
Percentile of i-th point is (i-1/3)/(n+1/3) * 100%. Unbiased estimator see https://www.itl.nist.gov/div898/handbook/prc/section2/prc262.htm

values
public static Percentile.Type[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (Percentile.Type c : Percentile.Type.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static Percentile.Type valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
