Abstract: We formulate the notion of a "good approximation" to a probability distribution
over a finite abelian group G . The quality of the approximating distribution is characterized
by a parameter ffl which is a bound on the difference between corresponding
Fourier coefficients of the two distributions. It is also required that the sample space
of the approximating distribution be of size polynomial in log jGj and 1=ffl. Such approximations
are useful in reducing or eliminating the use of... (Update)

...we get smaller sample spaces. Our considerations are motivated by a problem which was mentioned in recent work of Azar, Motwani and Naor [AMN], namely, how to construct in time polynomial in n a good approximation to the joint probability distribution of the random variables X 1...
