This paper indicates causality as the tool that unifies the analysis of both activations and connectivity of brain areas, obtained with fMRI data. Causality analysis is commonly applied to study connectivity, so this work focuses on demonstrating that also the detection of activations can be handled with a causality analysis. We test our method on finger tapping data, in which GLM and Granger C...

this paper empirically investigates the exchange rate effects of iranian rial against dollar (rial vs.us) on stock prices in iran. the sample period for the study has been taken from march 20, 2004 to march 20, 2010 using daily nominal exchange rate of rial /us and daily closing values of tehran stock exchange. generalized autoregressive conditional heteroskedasticity (garch) model has been use...

this world; though all the discussions are focused on the causal relationships in allthe scientific arguments. one of the methods to study the designed causal relationshipsobjectively is granger causality test. this paper aims to investigate the longtermcausal relationship between the stock price and dividends. the statisticalpopulation includes 180 active companies in stock exchange of tehran ...

The present study attempts to examine the casual relationship between foreign capital inflows and economic growth in India. Using the pair-wise Granger causality test (1969), this paper specifically examines casual relationship between foreign capital inflows and economic growth in India. The important observations emerge from pair-wise Granger causality test which shows there is the long-run e...

Ecological multivariate systems offer a suitable data set on which to apply recent advances in information theory and causality detection. These systems are driven by the interplay of various environmental factors: meteorological and hydrological forcing, which are often correlated with each other at different time lags; and biological factors, primary producers and decomposers with both autono...

Scientometric models can connect indicators via cross-country correlations, but these are not enough to assert causality. Sometimes a causal connection can be argued from the physical process. In other cases the causality or its direction is not clear, and the Granger test is often used to clarify the connection. Here it was shown that gross expenditures on R&D (GERD) Granger caused scientific ...

In this paper, an examination is made of the linkage between foreign direct investment and productivity in eight East Asian economies–China, Hong Kong SAR, Indonesia, Malaysia, Republic of Korea, Singapore, Taiwan Province of China and Thailand. The Granger causality test and the Toda-Yamamoto version of the Granger causality test are used to test if inflows of foreign direct investment “cause”...
