    Sammanfattning : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. LÄS MER

  3. 2. Zero Coupon Yield Curve Construction Methods in the European Markets

    Master-uppsats, KTH/Matematik (Avd.)

    Nyckelord :Zero coupon; Yield curve construction; Forward monotone convex spline; Cubic spline; Nelson Siegel; Nelson Siegel Svensson; Hedge; Interpolation; Parameterization; Evaluation; Principal component; Nollkupong; Yieldkurva; Forward monotone convex spline; Kubisk spline; Nelson Siegel; Nelson Siegel Svensson; Interpolering; Parameterisering; Utvärdering; Principalkomponent; Hedge;

    Sammanfattning : In this study, four frequently used yield curve construction methods are evaulated on a set of metrics with the aim of determining which method is the most suitable for estimating yield curves from European zero rates. The included curve construction methods are Nelson-Siegel, Nelson-Siegel-Svensson, cubic spline interpolation and forward monotone convex spline interpolation. LÄS MER
