Enclosing class:

OLSSolver

public static enum OLSSolver.Method
extends java.lang.Enum<OLSSolver.Method>

the methods available to solve an Ordinary Least Square problem

Enum Constant Summary

QR
an orthogonal decomposition method that is slow, but numerically stable (recommended)

SVD
allow approximation to truncate small singular values; this is an orthogonal decomposition method that is slower, but more numerically stable.

Method Summary

static OLSSolver.Method	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.

Method Detail

values

public static OLSSolver.Method[] 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 (OLSSolver.Method c : OLSSolver.Method.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OLSSolver.Method 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 name

java.lang.NullPointerException - if the argument is null
