Class SoP

java.lang.Object

marytts.machinelearning.SoP

public class SoP
extends Object

Contains the coefficients and factors of an equation of the form: if interceptTterm = TRUE solution = coeffs[0] + coeffs[1]*factors[0] + coeffs[2]*factors[1] + ... + coeffs[n]*factors[n-1] if interceptterm = FALSE solution = coeffs[0]*factors[0] + coeffs[1]*factors[1] + ... + coeffs[n]*factors[n]
