spectral decomposition is a powerful tool for analysis of seismic data. fourier transform determines the frequency contents of a signal. but for analysis of non-stationary signals, 1-d transform to frequency domain is not sufficient. in early years, transforming of seismic traces into time and frequency domain was done via windowed fourier transform, called a short time fourier transform (stft)...

various studies have been conducted to study the relationship between job involvement and organizational citizenship behavior but a very little work have been done to study the impact of both job involvement and organizational commitment on “organizational citizenship behavior”. thus the purpose of the study is to find out the relationship between job involvement, organizational commitment and ...

This study aimed at assessing the relationship between tax revenue and economic growth in Nepal. A Causal comparative research design was employed using time series data from fiscal year 1974/75 to 2019/20. Accordingly, GDP constant price considered dependent variable, income tax, excise duty, value-added customs duty as independent variables. Since all variables their log forms were stationary...

In this paper, I derive an expression for the asymptotic bias in the OLS estimator of the partial effect of a regressor on the dependent variable when there is reverse causality and all variables in the model are covariance stationary. I show that the sign of the asymptotic bias depends only on the signs of the bi-directional causal effects. JEL Codes: C10, C30.
