A modification of Burger's phi-normal approximation for the moments of grain-size data

Authors


ABSTRACT

This paper gives a modification of Burger's method of approximation for the moments of grain-size data. It is shown that formal integration can be carried out in conjunction with Burger's phi-normal interpolation scheme. This approach obviates Burger's recourse to a discrete numerical integration procedure because exact integration yields a computationally more efficient approximation formula for the moments.
