Non-Parametric Analysis of Rating Transition and Default DataPeter FledeliusRoyal&SunAlliance David LandoCopenhagen Business School - Department of Finance Jens Perch NielsenCity University London - Cass Business School Journal of Investment Management, Vol. 2, No. 2, Second Quarter 2004 Abstract: We demonstrate the use of non-parametric intensity estimation - including construction of pointwise confidence sets - for analyzing rating transition data. We find that transition intensities away from the class studied here for illustration strongly depend on the direction of the previous move but that this dependence vanishes after 2-3 years.
