net.finmath.marketdata.model.volatility.caplet.tenorconversion.TenorConverter

public class TenorConverter
extends Object

This class implements a caplet volatility tenor converter. Given a correlationprovider, the current caplet vol data and the new tenor it converts the volatilities to the new tenor using the method suggested in the paper by Schlenkrich.
