... moments of the month of first conception. A critical analysis of this method has shown that moment estimators of a and b are moderately reliable only within a specified range of values of a . Outside this range, either the estimators are extremely inefficient or their variances are not defined at all...

... for representing the length of interval to first conception leading to a live birth. Potter and Parker estimated the parameters of this distribution with the help of the first two moments. Majumdar and Sheps (1970) pointed out the limitations of these moment estimates and gave a method to obtain maximum likelihood...

This paper presents an algorithm to obtain the moment and maximum likelihood estimates of a and b from...

..., the parameters have been restricted to depend on the first two moments, instead of the first four. The number of independent parameters has thus been reduced to only three, and method shave been suggested for their estimates, using ancillary information which is usually provided in the census reports...
