Class ACERLogFunction

All Implemented Interfaces:
Function<Vector,Double>, RealScalarFunction, UnivariateRealFunction

public class ACERLogFunction extends AbstractUnivariateRealFunction
The ACER function in log scale (base e), i.e., \(log(\epsilon_k(\eta))\).

The R equivalent function is acer::acer.log_evaluate.
