Gram-charlier peak function
The Gram–Charlier A series (named in honor of Jørgen Pedersen Gram and Carl Charlier), and the Edgeworth series (named in honor of Francis Ysidro Edgeworth) are series that approximate a probability distribution in terms of its cumulants. The series are the same; but, the arrangement of terms (and thus the … See more We examine a continuous random variable. Let $${\displaystyle {\hat {f}}}$$ be the characteristic function of its distribution whose density function is f, and $${\displaystyle \kappa _{r}}$$ its cumulants. … See more Edgeworth developed a similar expansion as an improvement to the central limit theorem. The advantage of the Edgeworth series is that the error is controlled, so that it is a true asymptotic expansion.
