TL;DR: It is shown that, under certain not restrictive conditions, the resulting estimators are consistent and, suitably normalized, asymptotically normal, even if the model is misspecified.
Abstract: This paper studies properties of parameter estimators obtained by minimizing a distance between the empirical probability generating function and the probability generating function of a model for count data. Specifically, it is shown that, under certain not restrictive conditions, the resulting estimators are consistent and, suitably normalized, asymptotically normal. These properties hold even if the model is misspecified. Three applications of the obtained results are considered. First, we revisit the goodness-of-fit problem for count data and propose a weighted bootstrap estimator of the null distribution of test statistics based on the above cited distance. Second, we give a probability generating function version of the model selection test problem for separate, overlapping and nested families of distributions. Finally, we provide an application to the problem of testing for separate families of distributions. All applications are illustrated with numerical examples.

27 Mar 2001TL;DR: In this article, a method of estimating a measure of randomness of a function of at least one representative value of a random variable is constructed to have the steps of obtaining the at least 1 random variable, determining the at most one representative values of the obtained at least single random variable; determining a first statistic of the first statistic; and transforming the obtained first statistic into a second statistic, using the determined gradient.
Abstract: A method of estimating a measure of randomness of a function of at least one representative value of at least one random variable is constructed to have the steps of obtaining the at least one random variable; determining the at least one representative value of the obtained at least one random variable; determining a first statistic of the obtained at least one random variable; determining a gradient of the function with respect to the determined at least one representative value; and transforming the obtained first statistic into a second statistic of the function, using the determined gradient The step of transforming may be adapted to transform the first statistic into the second statistic, such that the second statistic responds to the first statistic more sensitively in the case of the gradient being steep than in the case of the gradient being gentle

TL;DR: A model for the RAFT polymerization following the slow fragmentation approach was developed in order to obtain the full molecular weight distribution (MWD) using probability generating functions (pgf) to provide a detailed characterization of the polymer that could be of great help for grasp the process fundamentals.
