It should be noted that the Legendre series is but a special case of the Gegenbauer, Ferrer and Jacobi series [16,29,32]. 2.3. Example (Gram Charlier series of type A) The Legendre series of Example 2.2 is only applicable to functions with compact support. If f has support on the real line, one can use a special form of the Herte series, the Gram Charlier series of type A. The strategy followed in this paper ....
