TSPred (version 5.1)

evaluating: Prediction/modeling quality evaluation

Description

Constructor for the evaluating class representing a time series prediction or modeling fitness quality evaluation based on a particular metric. The evaluating class has two specialized subclasses fitness and error reagarding fitness criteria and prediction/modeling error metrics, respectively.

Usage

evaluating(eval_func, eval_par = NULL, ..., subclass = NULL)
fitness(eval_func, eval_par = NULL, ..., subclass = NULL)
error(eval_func, eval_par = NULL, ..., subclass = NULL)

Arguments

eval_func

A function for computing a particular metric.

eval_par

List of named parameters required by eval_func.

...

Other parameters to be encapsulated in the class object.

subclass

Name of new specialized subclass object created in case it is provided.

Value

An object of class evaluating. A list usually containing at least the following elements:

func

A function for computing a particular metric.

par

Particular parameters required by func.
