Yıldırım et al. [5] estimated the model parameters and introduced a test statistic in one-way classification AR(1) model under the assumption of independently and identically distributed (iid) error terms having Student’s t distribution, see also [4]. In this study, we extend their study to linear contrasts which is a well-known and widely used comparison method when the null hypothesis about the equality of the treatment means is rejected, see [3], [4]. See also [1] and [2] in the context of ANOVA. A test statistic for the linear contrasts is introduced. A comprehensive simulation study is done to compare the performance of the test statistic with the corresponding normal theory test statistic. At the end of the study, a real life data is analysed to show the implementation of the introduced test statistic.

Anthropic likelihood for the cosmological constant and the primordial density perturbation amplitude Hong, Sungwook E.; Stewart, Ewan D.; Zoe, Heeseung (2012-04-09) Weinberg et al. calculated the anthropic likelihood of the cosmological constant Lambda using a model assuming that the number of observers is proportional to the total mass of gravitationally collapsed objects, with mass greater than a certain threshold, at t -> infinity. We argue that Weinberg's model is biased toward small Lambda, and to try to avoid this bias we modify his model in a way that the number of observers is proportional to the number of collapsed objects, with mass and time equal to certain ...
Comment on 'Rockfall avalance deposits associated with normal faulting in the NW of the Cankiri basin: implications for the post-collisional tectonic evolution of the Neo-Tethyan suture zone' by G. Seyitoglu, N. Kazanci, L. Karadenizli, S. Sen, B. Varol, and T. Karabiyikoglu Kaymakcı, Nuretdin (Wiley, 2003-04-01) Seyitoglu et al. (2000) described their interpretation, based on a single fault surface and rockfall avalanche deposits previously mapped as a W-vergent thrust klippen above the Neogene successions in the Hancili Basin, that in central Anatolia there was a single extensional basin throughout the Miocene - Early Pliocene. It was later fragmented by a structural high of Neo-Tethyan ophiolitic basement bounded by an E-vergent thrust fault in the east along the western margin of the Cankiri Basin and a west-dip...
Searching for subspace trails and truncated differentials Leander, Gregor; Tezcan, Cihangir; Wiemer, Friedrich (2018-01-01) Grassi et al. [Gra+16] introduced subspace trail cryptanalysis as a generalization of invariant subspaces and used it to give the first five round distinguisher for Aes. While it is a generic method, up to now it was only applied to the Aes and Prince. One problem for a broad adoption of the attack is a missing generic analysis algorithm. In this work we provide efficient and generic algorithms that allow to compute the provably best subspace trails for any substitution permutation cipher.
Strongly convergent method to solve one-dimensional quantum problems Taşeli, Hasan (1997-07-01) Vargas et al. [Phys. Rev. E 53, 1954 (1996)] presented a numerical matrix method to solve the one-dimensional Schrodinger equation subject to Dirichlet boundary conditions. It is a well-known fact that the eigensolutions of such a confined system converge asymptotically to those of the corresponding unbounded problem as the boundary value increases. However, it is verified computationally that the results given by Vargas et al. are inaccurate, especially for the excited states of the perturbed oscillator Ha...
International physical education teacher education physical activity content knowledge study Ward, Phillip; İnce, Mustafa Levent; Iserbyt, Peter; Insook, Kim; Lee, Yun Soo; Lee, Weidong; Sutherland, Sue (null; 2013-04-23) Background/Purpose Ball et al. (2008) categorized knowledge for teaching into two domains: Common Content Knowledge (CCK) and Specialized Content Knowledge (SCK). As a general rule CCK can be viewed as knowing how to perform an activity and SCK as knowing how to teach CCK (e.g., teaching progressions). Recent research has shown that many teachers do not acquire SCK sufficiently well enough to teach (Lee, 2010; Kim 2011). Method We examined the extent to which CK classes include CCK and SCK in 77 PETE progr...
