If a function moments() is introduced, I would suggest to make it more general: e.g. moments(x,i) could return up to the i-th moment of x in a i-column matrix, with i>0. Otherwise I would prefer the two functions skew() and kurt() over one function moments(). cheers, sven _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
