A new heteroskedastic hedonic regression model is suggested. It takes into account time-varying volatility and is applied to a blue chips art market. Furthermore, a nonparametric local likelihood estimator is used. This estimator is more precise than the often used dummy variables method. The empirical analysis reveals that errors are considerably non-Gaussian, and that a student distribution w...

This study aims to (1) analyze the structure of household income farmers during covid-19 pandemic; and (2) resilience rice in Lebak swamp land factors that influence it. The research method used is a survey with sample 60 farmers, which are divided into 2 strata, IP100 IP200 farmers. data analysis for first purpose descriptive tabulation, while second objective uses multiple regression analysis...

Using a large sample of 46,467 residential properties spanning 1999-2005, we demonstrate using matched pairs that, relative to linear hedonic pricing models, artificial neural networks (ANN) generate significantly lower dollar pricing errors, have greater pricing precision out-of-sample, and extrapolate better from more volatile pricing environments. While a single layer ANN is functionally equ...

This article provides an introduction to the burgeoning academic literature on Bayesian Vector Autoregressions, benchmark models for applied macroeconomic research. We first explain Bayes’ theorem and the derivation of the closed-form solution for the posterior distribution of the parameters of the model given data. We further consider parameter shrinkage, a distinguishing feature of the prior ...

We make use in this article of a testing procedure suggested by Robinson (1994) for testing deterministic seasonality versus seasonal fractional integration. A new test statistic is developed to simultaneously test both, the order of integration of the seasonal component and the need of seasonal dummy variables. Finite-sample critical values of the tests are computed and, an empirical applicati...

OBJECTIVES To examine the association between use of a dummy (pacifier) during sleep and the risk of sudden infant death syndrome (SIDS) in relation to other risk factors. DESIGN Population based case-control study. SETTING Eleven counties in California. PARTICIPANTS Mothers or carers of 185 infants whose deaths were attributed to SIDS and 312 randomly selected controls matched for race o...

T his paper aims to understand the structure and determinants of international bank l ending among APEC economies. Specifically, this paper first aims to analyze whether Australia Canada Japan Chinese Taipei and the United States, which are the only APEC members for which international borrowing data are available, tend to lend more intensively to other APEC members than to non-APEC countries ....

This study aims to determine whether Managerial Ownership, Institutional Profitability and Cash Flow affect Financial Distress. The population in this are 386 companies with secondary data sources derived from the financial reports of manufacturing listed on IDX for 2020-2021. selection research sample used a purposive sampling technique so that samples obtained were 149 companies. method is qu...

This paper presents a rail-to-rail constant-gm operational amplifier input stage. The proposed circuit changes the tail current of the input differential pairs dynamically for a constant-gm by using dummy input differential pairs. The problem which causes total gm variation is input pairs and dummy input pairs can not take effect at the same time with the common-mode input voltage changes, beca...
