A New Random Normalizing Approach to the M Test without Recursive Estimations

چکیده

The traditional M test requires a consistent estimation of the asymptotic variancecovariance matrix of the estimated moments (the AVC matrix). By extending the approach of Kiefer, Vogelsang, and Bunzel (KVB; 2000, Econometrica), Kuan and Lee (KL; 2006, Journal of the American Statistical Association) contributed a new type of M test without the AVC matrix estimation but with recursive model estimations. By focusing on testing model correctness, we propose another new type of M test without the AVC matrix estimation and without recursive model estimations. The proposed approach is based on a “discretized” random normalizing matrix. It has computational and theoretical advantages over the KVB-KL approach in testing model correctness. In particular, the proposed M test statistic is simpler to compute, and has a F distribution in large samples. Our M test can also be designed to be asymptotically equivalent to the traditional M test and asymptotically more powerful than the KVB-KL M test under local alternatives. JEL classification: C12, C15

A Recursive Approximation Approach of non-iid Lognormal Random Variables Summation in Cellular Systems

Co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. As the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal Random Variables (RVs) which has no closed-form expression. Assuming independent, identically distributed (iid) RVs, the...

Improving the Performance of Bayesian Estimation Methods in Estimations of Shift Point and Comparison with MLE Approach

A Bayesian analysis is used to detect a change-point in a sequence of independent random variables from exponential distributions. In This paper, we try to estimate change point which occurs in any sequence of independent exponential observations. The Bayes estimators are derived for change point, the rate of exponential distribution before shift and the rate of exponential distribution after s...

A New Recursive Formulation for the Mixed Redundancy Strategy in Reliability Optimization Problems

One of the common approaches for improving the reliability of a specific system is to use parallel redundant components in subsystems. This approach, which is known as the redundancy allocation problem (RAP), includes the simultaneous selection of the component type and its level for each subsystem in order to maximize the system reliability.Traditionally, there are two redundancy strategies, n...

Limit distribution of the degrees in scaled attachment random recursive trees

We study the limiting distribution of the degree of a given node in a scaled attachment random recursive tree, a generalized random recursive tree, which is introduced by Devroye et. al (2011). In a scaled attachment random recursive tree, every node $i$ is attached to the node labeled $lfloor iX_i floor$ where $X_0$, $ldots$ , $X_n$ is a sequence of i.i.d. random variables, with support in [0,...
