Trend growth in total factor productivity (TFP) is unobserved; it evolves continually over time. That assumption is inherent in the use of the Hodrick-Prescott or other bandpass filters to extract trends. Similarly, the Kalman filter/unobserved-components approach assumes that changes in the trend growth rate are normally distributed. In fact, some changes to the trend growth rate of total fact...

salinity and drought stress are among the common environmental factors which adversely affect germination and growth of plants. this experiment was conducted to evaluate the effects of salinity and drought stress on turnip seed germination and early growth in seed lab of college of agriculture, university of tehran, during 2010. the experimental design was a complete randomized block with three...

Stock trend forecasting is a one of the main factors in choosing the best investment, hence prediction and comparison of different firms’ stock trend is one method for improving investment process. Stockholders need information for forecasting firm’s stock trend in order to make decision about firms’ stock trading. In this study stock trend, forecasting performs by data mining algorithm. It sho...

We conduct both an approximate Bayesian Model Averaging (BMA) and an exact Bayesian analysis to incorporate break date uncertainty of the mean growth rate into the trend-cycle decomposition of U.S. real GDP. Our results suggest a structural break in mean growth rate of U.S. real GDP in 1970s. Comparing to the models assuming fixed break date, we find higher uncertainty in the posterior density ...

Rising rates of economic growth during the 1990s have inspired speculation about a shift in the underlying growth rates of technology and productivity. This paper considers the adjustment dynamics of such a change in a basic neoclassical framework that incorporates stochastic growth. Simulations of the model suggest that the dynamics of capital stock adjustment in response to changing growth pa...

background: birth weight is considered as the most important index of neonates' growth as well as the most important determinant of infants' mortality. this study was conducted to investigate the growth pattern in normal, low and very low birth weight neonates for 18 months in the health care centers of isfahan, iran. materials and methods: in a cross-sectional and retrospective study, 214 neon...

BACKGROUND Sensors detect the rate and direction of glucose trend. They need to be accurate and reproducible as could be evidenced by strong agreement between multiple sensors. We evaluated this relationship through simultaneously worn glucose sensors using several methods of slope analysis. METHODS Ten type 1 diabetic, insulin pump-treated subjects were studied while simultaneously wearing t...

The rapid increase in U.S. economic growth during the late 1990s inspired speculation that an acceleration in the rate of technological progress had given rise to an increase in potential output growth. This paper considers the transition dynamics associated with such a change using a general equilibrium framework that incorporates stochastic growth trends. The model suggests that transition dy...
