The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. These values are typically calculated using a tree-based model, built for the entire yield curve (as opposed to a single yield to maturity), and therefore capturing exercise behavior at each point in the option's life as a function of both time and interest rates; see Lattice model (finance) Interest rate derivatives. Unlike the lambda, which is an elasticity (a percentage change in output for a percentage change in input), the modified duration is instead a semi-elasticitya percentage change in output for a unit change in input. 1 The Bayer designation naming scheme for stars typically uses the first Greek letter, , for the brightest star in each constellation, and runs through the alphabet before switching to Latin letters. x "Basically, I just loved what I saw.
