Recovering Risk-Neutral Probability Density Functions from Options Prices using Cubic Splines Ana Margarida Monteiro Reha H. T ut unc u y Lu s N. Vicentez July 20, 2004 Abstract We present a new approach to estimate the risk-neutral probability density function (pdf) of the future prices of an underlying asset from the prices of options written on the asset. The estimation is carried out in

Probability Density Function of the Euclidean Distance

In this paper, we explore a new distance metric that leads to an analytical formula in the case where the probability density functions correspond to Gaussian Mixtures. It is obvious that the distance metric we choose to employ is of major importance for the performance of the CBIR system. It is evident that the query results are explic- itly affected by the metric used. Also, a

Not all pdf distance measures are tractable since the true probability is always unknown. In the following, we formulate two tractable cost functions that are related to the ISE and the K–L divergence for an output probability density estimator based on the GPR model.
