Empirical threshold

The frequency of a variant in the general population is a key criterion used in the clinical interpretation of sequence variants. With certain exceptions, such as founder mutations, the rarity of a variant is a prerequisite for pathogenicity.

The research investigated to compress ECG signals using JPEG2000. Also proposed is a method of ECG signal de-noising based on Hilbert-Huang transform. This method uses empirical mode decomposition to decompose the signal into several intrinsic mode functions (IMFs) and then the noisy IMFs are removed by using soft-threshold method.

One of the objectives of the EMPIR project 16ENV04 “Preparedness” is the harmonization of methodologies for the measurement of doses with passive dosimetry systems for environmental radiation monitoring in the aftermath of a nuclear or radiological event. In such cases, measurements are often performed at low radiation dose rates, close to the detection limit of the passive systems.

The proposed methodology yields very low equal error rate of 0.5% and the authentication accuracy of 99.5%, which are considered suitable and efficient for real-time implementation. The proposed method can be a useful resource for identifying illegal invasion and is valuable in securing the system as a correlative or substitute form of client validation.

The paper presents a discussion of stock market liquidity in a frontier market after the financial crisis. The paper defines dimensions of stock market liquidity and indicates possible liquidity measures which could be applied to analyze liquidity on a stock exchange in Vietnam. The empirical result shows the aggregate liquidity, which captures various dimensions of liquidity through eight liquidity measures based on a daily basis during the period from 2011 to 2018.

In this study, we apply Panel Threshold Model (Hansen, 1999) to examine whether there is optimal asset scale for interest spread to affect banks' profits. The empirical results demonstrate the existence of three thresholds, which divide banks into four groups into four groups according to asset scale. When asset scales of banks are in the 3rd capital group, banks profit by the widening in loan-deposit interest spread. For the other three groups, however, the relationship between profit and loan-deposit spread is negative.

This paper examines the statistical relationship between banks’ return on equity on one hand, and their size (as measured by inflation-adjusted total assets) and capital structure on the other, using uses a set of panel data collected by the first author in 2014. The empirical approach applied allows for heterogeneity across observational units as well as nonlinearity and non-additivity in the conditional mean function, thus facilitating the identification of more complex forms of structural dependence that might remain undetected when using classical linear regression techniques.

Hansen’s (1999) panel threshold regression model is applied in this study to investigate the correlation between bank size and bank earnings volatility in 14 Chinese banks. These data were adopted after the Lehman Brothers bankruptcy was announced in 2009Q4. The data used in this study cover the period from 2009Q1 to 2013Q1. The dependent variable is bank earnings volatility, whereas bank size is the independent and threshold variable. Empirical results show the significance of a single threshold on bank size and return on asset (ROA) earnings volatility.

This paper empirically examines how the local financial development and institutions influence a country’s capacity to take advantage from remittances over the period 1985-2014. We use a dynamic panel threshold model (see Hansen, 1999 and Caner and Hansen, 2004) to estimate remittances thresholds for long-term economic growth. The evidence strongly suggests that the impact of remittances on economic growth depends on the level of financial development and the institutional environment.

The overall objective is based on the fundamental theories of capital structure and empirical research on capital structure and financial performance of the firm, whereby the author develops and analyzes the relationship between capital structure and financial performance. It then determines the optimal debt threshold for the Tourism and travel companies (TTCs) of Hue City.

This paper aims to provide empirical evidence of Vietnam’s public debt threshold. The data of the annual country's public debt in the 1990 - 2010 period, the threshold model by Hansen (1996, 2000), and the OLS estimation method are employed to test threshold effects and estimate the value of the public debt threshold.

This paper presents results from experiments in automatic classification of animacy for Norwegian nouns using decision-tree classifiers. The method makes use of relative frequency measures for linguistically motivated morphosyntactic features extracted from an automatically annotated corpus of Norwegian. The classifiers are evaluated using leave-oneout training and testing and the initial results are promising (approaching 90% accuracy) for high frequency nouns, however deteriorate gradually as lower frequency nouns are classified.

Critical loads, and other approaches that use models or empirical observations to link deposition with effects, provide tools that enable resource managers and policymakers to evaluate tradeoffs between the costs of more stringent emissions controls and the benefits of ecosystem services provided by healthy ecosystems. A critical loads approach can be used to synthesize scientific knowledge about air pollution thresholds that cause adverse impacts or ecosystem change.

Financial data are conventionally represented in numeric format for data mining purpose. However, recent works have demonstrated promising results of representing financial data symbolically. For an instance, Kovalerchuk et al. (2002) argues that symbolic relational data mining is more suitable in incorporating background knowledge. Their proposed methodology outperforms numeric financial data in generating IF-Then rules. In (Ting et al.
