In this paper, we study a first order random coefficient autoregressive model with Laplace distribution as marginal. A random coefficient moving average model of order one with Laplace as marginal distribution is introduced and its properties are studied. By combining the two models, we develop a first order random coefficient autoregressive moving average model with Laplace marginal and discus...

in this research genetic and phenotypic parameters were estimated using linear and threshold models, for reproductive traits, data from 6 large industrial dairy herd of east azerbaijan province collected by agriculture jihad organization during 10 years (2001-2010). best linear unbiased predictions of traits breeding values were estimated using restricted maximum likelihood method by wombat sof...

Two-part models are an attractive approach for analysing longitudinal semicontinuous data consisting of a mixture of true zeros and continuously distributed positive values. When the population-averaged (marginal) covariate effects are of interest, two-part models that provide straightforward interpretation of the marginal effects are desirable. Presently, the only available approaches for fitt...

In this appendix, we first describe the mathematical derivation of the marginal likelihood of model Mh: P (G|Mh) (Section 2). Then we show four equivalent formulas for solving P (G|Mh) (Section 3). After that, we show how to obtain the marginal likelihood of model Ml from the solution to the marginal likelihood of model Mh (Section 4). Finally, we show that the overall computational complexity ...

For square contingency tables with the same row and column ordinal classifications, we propose a model of quasi-symmetry using the row and column marginal ridits scores. Using the proposed model, the model of equality of marginal mean ridits and the model of equality of marginal variance ridits, we give a theorem such that the symmetry model holds if and only if all these models hold. Moreover,...

background and aim: an important criterion for success assessment of implant-supported prostheses is marginal fit. vertical and horizontal discrepancy can result in loosening of the prosthetic screw, crestal bone resorption, peri-implantitis and loss of osseointegration. despite careful attention to waxing, investing, and casting, marginal discrepancies are inevitable. the aim of this study was...

objective: this experimental in vitro study compared marginal adaptation of indirect composite, glass-ceramic inlays and direct composite. materials and methods: seventy-five recently extracted human molars were randomly divided into three groups (n=25) and mesio-occluso-distal cavities with the same dimensions were prepared in the teeth. indirect composite and glass-ceramic inlays were fabrica...

The marginal proportional hazards frailty model for multivariate failure time data characterizes the intracluster dependency with the frailty model while formulating the marginal distributions with the proportional hazards model. The gamma frailty distribution has been widely used to model intracluster dependency because of its simple interpretation and mathematical tractability. Glidden (2000)...

Abstract: For square contingency tables with the same row and column ordinal classifications, this paper proposes the quasi-symmetry model based on the marginal ridits. The model indicates that the log-odds that an observation will fall in the (i, j) cell instead of in the (j, i) cell, i < j, is proportional to the difference between the average ridit score of row and column marginal distributi...

This paper shows how the sampling distribution of estimates of deadweight costs from taxation can be simulated and used to construct confidence intervals. The method is applied to the models and data developed by Diewert and Lawrence (1994, 1996) to study the marginal costs of taxation in New Zealand but the methods proposed have more general relevance. The application shows that the data are u...
