Abstract

The estimation of the two parameters of the quasi geometric series distribution (QGSD) of Mishra and Singh (2000) by the method of moments is not possible as its moments appear in terms of various series. The likelihood equations are also not directly solvable. Another version of the (QGSD) , the first two moments of which appear in simple algebraic forms and which has the same nature and behaviour as that of Mishra and Singh’s version, has been obtained. The estimation of parameters thus becomes simple by the method of moments. This version has been fitted to some data-sets to test its goodness of fit.
