We consider the problem of model selection in vector autoregressive model with Normal innovation. Tests such as Vuong's and Cox's tests are provided for order and model selection, i.e. for selecting the order and a suitable subset of regressors, in vector autoregressive model. We propose a test as a modified log-likelihood ratio test for selecting subsets of regressors. The Europe oil prices, ...
Purpose: The aim of the present study is to investigate the effect of low-power Helium-Neon laser (LPL) on collagen fibril thickness of incisized medial collateral ligament of knee joint (MCL) in rat. Materials and Methods: MCL of right hind limb of 35 male adult sprague Dawley rat under general anesthesia were transversly incisized. Rats were randomly divitded into normal, control, first lase...
We introduce a family of operators called the $k$-quasi-$(n,m)$-power normal operators. Such includes normal, $n$-normal and $(n,m)$-power An operator $T \in {\mathcal B}({\mathcal H})$ is said to be if it satisfies $$T^{*k}\bigg(T^nT^{*m}-T^{*m}T^n\bigg)T^k=0,$$ where $k,n$ $m$ are natural numbers. Firstly, some basic structural properties this established with help special kind matrix represe...
