These estimators are based on an analytical, usually approximative representation of the underlying density. We study approximative densities obtained by the WKB method. The results are applied in the context of a Libor market model.application/pdfeng510American optionsSensitivitiesMonte-Carlo methodsWKB expansionsReport
