Good day everyone, I want to use the Gram-Charlier series expansion to model some data. To do that, I need functions to:
1) Calculate 'n' moments from given data 2) Transform 'n' moments to 'n' central moments, or 3) Transform 'n' moments to 'n' cumulants 4) Calculate a number of Hermite polynomials Are there R-functions to do any of the above? (mean, sd and cum3 are very limited) Thank you for your help, Augusto -------------------------------------------- Augusto Sanabria. MSc, PhD.
