In this work we suggest a methodology to obtain the membership of a non observable parameter through implicit information. To this aim we prot from the interpretation of membership functions as coherent conditional probabilities. We develop full details for the well known Black and Scholes pricing model where the membership of the volatility parameter is obtained from a sample of either asset prices or market prices for options written on that asset.

Abstract
In this work we suggest a methodology to obtain the membership of a non observable parameter through implicit information. To this aim we prot from the interpretation of membership functions as coherent conditional probabilities. We develop full details for the well known Black and Scholes pricing model where the membership of the volatility parameter is obtained from a sample of either asset prices or market prices for options written on that asset.File in questo prodotto:
