In this paper, we propose a new two-parameter biased estimator in gamma regression models when there is collinearity among the regressors. We investigate mean squared error (MSE) properties of newly proposed estimator. Moreover, provide some theorems to compare estimators existing ones. conduct Monte Carlo simulation study under different designs sense MSE. real data application show usefulness...

A family of pentagonal quasicrystals can be defined by projecting a section the five-dimensional cubic lattice to two dimensions. single parameter, sum intercepts $\mathrm{\ensuremath{\Gamma}}={\ensuremath{\sum}}_{j}{\ensuremath{\gamma}}_{j}$, describes this defining cut in space. Each value $0\ensuremath{\le}\mathrm{\ensuremath{\Gamma}}\ensuremath{\le}\frac{1}{2}$ defines unique local isomorph...

Understanding the subgraph distribution in random networks is important for modeling complex systems. In classic Erdos networks, which exhibit a Poissonian degree distribution, the number of appearances of a subgraph G with n nodes and g edges scales with network size as approximately N(n-g). However, many natural networks have a non-Poissonian degree distribution. Here we present approxima...

We address the problem of computing optimal policies for a finite-horizon newsvendor model with censored demand and perishable inventory. By combining an earlyperiod optimization based grid search with easily computable late-period bounds, we are able to handle a broad range of demand distributions and prior specifications. The grid-search is performed on a discretization of the demand-decision...

In this paper, the wireless system consisting of macrodiversity selection combining (SC) receiver and two microdiversity SC receivers under the influence of small scale fading and large scale fading, as well as co-channel interference is observed. Small scale fading has Weibull distribution. Correlated large scale fading is described by Gamma distribution. Co-channel interference is disturbed b...

We study fermions at quantum criticality with extremely retarded interactions of the form $V({\ensuremath{\omega}}_{l})=(g/|{\ensuremath{\omega}}_{l}{|)}^{\ensuremath{\gamma}}$, where ${\ensuremath{\omega}}_{l}$ is transferred Matsubara frequency. This system undergoes a normal-superconductor phase transition critical temperature $T={T}_{c}$. The order parameter frequency-dependent gap function...

In this paper, a new class of five parameter gamma-exponentiated or generalized modified Weibull (GEMW) distribution which includes exponential, Rayleigh, Weibull, exponentiated gamma gamma-modified gamma-Weibull, gamma-Rayleigh and gamma-exponential distributions as special cases is proposed studied. Mathematical properties including moments, mean deviations, Bonferroni Lorenz curves, order st...
