(2014). In order to test GoF in binary response models such as the occupancy model, we always have to aggregate the binary response in some way. Clearly, many such aggregations are possible and it is not a priori clear which one is best in order to indicate a particular assumption ...
D. J. Best, N. I. Fisher 摘要: The only parametric model in current use for axial data from a rotationally symmetric bipolar or girdle distribution on the sphere is the Watson distribution. This paper develops methods for evaluating the model as a fit to data using graphical and formal ...
Note that it is possible to get a negative R-square for equations that do not contain a constant term. Because R-square is defined as the proportion of variance explained by the fit, if the fit is actually worse than just fitting a horizontal line then R-square is negative. In this cas...
In general, those approaches give similar results and none of them performs uniformly the best. In addition, among those estimators, the DerSimonian-Laird (DL) method is most commonly used. Therefore, in this paper the DL estimator is used. The parameter, τ2, which measures the between-...
Finally, a simulation study, considering a wide set of distributions mostly used in applications, is conducted to compare the proposed test with its classical competitors. The study gives some indications to locate such situations where the Girone-Cifarelli test performs at its best, notably over ...
Now the information matrix ratio (IMR) is defined as (7)≔Ψ(θ)≔−H(θ)−1C(θ). Our test problem is the reformulated general test problem of White [41]: H0:Ψ(θ)=IpagainstH1:Ψ(θ)≠Ip, where Ip is the p-dimensional identity matrix. To calculate the corresponding test...
