WebB. Preliminaries For the Method of Moments It is likely in practice that the values of a, v, and p will be unknown and must be estimated. Toward that end we appeal to the method of moments using the logarithm of the variable X. Let Zi = In (X,/a)' = p(ln Xi - In a), (10) where the X, are defined as in Section IIIA. Furthermore, we denote the kth WebMay 11, 2014 · This process will also be cost-effective and will minimize unwanted side effects due to systemic drug distribution in the lung ... in the cavity using a Finite Volume Method.
