Probabilists and fuzzy fanatics are likely to disagree approximately which philosophy is healthier they usually not often interact. consequently, textbooks frequently recommend just one of those tools for challenge fixing, yet now not either. This e-book, with contributions from 15 specialists in chance and fuzzy good judgment, is an exception.

3 An approximation of the lognormal-cdf 37 Fig. 05 running an IEE Finally, it can be pointed out that the new IEE is an excellent method for the approximation of exercise probabilities, even if the underlying random variable is lognormal- or lognormal-like distributed and the pdf does not exist in closed-form. Hence, the IEE can be applied for the approximation of the single exercise probabilities given an underlying random variable which is composed by a sum of multiple lognormal-distributed random variables.

Nevertheless, we will see in the following that the application of the EE remains very accurate and efficient. Given the mean µy and the standard deviation σy of a normal-distributed random variable y we obtain the pdf of a lognormal-distributed random variable x by (log(x)−µy )2 − 1 2σy2 √ e p(x) = , xσy 2π together with the moments α(m) = emµy + m2 2 2 σy . 2) we can compute the cumulants of a lognormal-distributed random variable x as follows 26 3 The Edgeworth Expansion 2 -pdf Fig. 4 Approximation error running an EE of a χ10 cum(n) = n!

31) together with the modified (log) strike price k˜ = log (P(t, T1 )K) . Hence, we directly obtain Q ˜ Q ˜ k − K · Πt,0 k , CBO1 (t, T0 , T1 ) = P(t, T1 )−1 Πt,1 with the probabilities Q [k] = EtQ e− Πt,a T0 t r(s)ds+aX(T0 ,T1 ) 1X(T0 ,T1 )>k˜ for a ∈ {0, 1} . Again, starting from the transform Θt (z) = EtQ e− T0 t r(s)ds+zX(T0 ,T1 ) we can show that the exponential affine guess holds for Θt (z) = P(t, T0 )ezX(t,T0 )+A(t,z) . g. 1). 3 Pricing of coupon bond options 57 and ft,2 (φ ) = eiφ (X(t)− 2 Λ (t))− 1 φ2 2 Λ (t) , together with the variance N 1 i σ (T0 , T1 )2 1 − e−2βi (T0 −t) .
