The aim of this work is to present a Matlab implementation of different methods for estimating the term structure of interest rate. More precisely, we implement the exponential functional form of Nelson-Siegel and polynomial spline methods (with or without penalty term), considering both coupon...

We investigate the time behaviour of the Italian MIB30 stock index collected every minute during two months in the period from May 17, 2006, up to July 24, 2006. We find short-range correlations in the price returns and, on the contrary, a long persistent time lag and slow decay in the...
