This package estimates a mix of lognormal distributions from interest-rate option data This package provides the estimation of implied probability density functions (pdf) from options data. The pdf's take the form of a mix of lognormal distributions. The methods used in the routines are discussed in the paper: Soderlind, P., and L. E. O. Svensson (1997), "New Techniques to Extract Market Expectations from Financial Instruments", Journal of Monetary Economics, 40, 383-429.
