MeanSquaredError

class MeanSquaredError<T> @JvmOverloads constructor(incarnation: Incarnation<T, *>, localCorrectValueMolecule: String, localCorrectValueProperty: String, statistics: String, localValueMolecule: String, localValueProperty: String) : Extractor<Double>

Exports the Mean Squared Error for the concentration of some molecule, given another molecule that carries the correct result. The correct value is extracted from every node, then the provided {@link UnivariateStatistic} is applied to get a single, global correct value. Then, the actual value is extracted from every node, its value is compared (subtracted) to the computed correct value, it gets squared, and then logged.

Parameters
