Development of new commercialized products and recognized that are increasingly innovative promising. Among the ingredients suit characteristics, there is hydrolyzed collagen Nile tilapia (Oreochomis niloticus), extracted from skin some promissory to be discarded, as an alternative due its nutritional technological characteristics. Considering importance innovation in food market use healthy su...

We examine the predictive value of tail risks oil returns for realized variance using monthly data modern industry (1859:10–2020:10). The Conditional Autoregressive Value at Risk (CAViaR) framework is employed to generate both 1% and 5% VaRs across four variants CAViaR framework. find evidence in-sample out-of-sample predictability emanating from risks. Given importance real-time oil-price vola...

This study examines the out-of-sample predictability of market risks measured as tail for stock returns eight advanced countries using a long-range monthly data over century. We follow Conditional Autoregressive Value at Risk (CAViaR) Engle and Manganelli (2004) to measure consequently, we produce results both 1% 5% VaRs across four variants (Adaptive, Symmetric absolute value, Asymmetric slope...

The objective of this study is to assess the performance of patient-specific segment-specific (PSSS) synthesis in QRST complexes using CAVIAR, a new method of the serial comparison for electrocardiograms and vectorcardiograms. A collection of 250 multi-lead recordings from the Common Standards for Quantitative Electrocardiography (CSE) diagnostic pilot study is employed. QRS and ST-T segments a...

The objective of this study was to compare biological parameters such as length, weight, age, caviar production indices, caviar/weight, growth, condition factor and sex ratios of Persian sturgeon (Acipenser persicus Borodin, 1897) and Russian sturgeon (A. gueldenstaedti Brandt & Ratzeburg, 1833) in the Caspian Sea during 1990-2014. The results showed that a variety of differences between this t...

Statistical volatility models rely on the assumption that the shape of the conditional distribution is fixed over time and that it is only the volatility that varies. The recently proposed conditional autoregressive value at risk (CAViaR) models require no such assumption, and allow quantiles to be modelled directly in an autoregressive framework. Although useful for risk management, CAViaR mod...

Black caviar is often thought to be a typically Russian luxurious food product. Recently, its production has extended due sturgeon aquaculture development. The analysis of the geographical affinities full-cycle companies and their aquaculture-sourced black implies that majority them employs Caviar brand and/or refers traditions history. However, names, brands, product positioning several tend m...
