WebThis paper aims to establish whether the Romanian energy market has an influence on the good running of the associated capital market. In order to achieve this objective, we approached a series of econometric techniques that allowed us to study the cointegration between variables, the presence of short-term or long-term causality relationships, and the … WebTo ensure a robust result, the study applied the ARDL bounds testing approach to cointegration, the Zivot–Andrew structural break test, and the Bayer–Hanck combine cointegration analysis. The causality analysis, was checked using the VECM model and this was validated using the innovative accounting and the impulse response test. relief valve on galbreath jib

WebAbstract This paper develops a limiting theory for Wald tests of weak exo- geneity in error correction models (ECMs). It is well known that Wald statistics on cointegrated systems may involve nonstandard distribu- tion and nuisance parameters, ifI(1) variables are not negligible in the statistics. WebSo for an intercept inside the cointegration relation we can either pass "ci" as deterministic or np.ones (len (data)) as exog_coint if data is passed as the endog argument. This ensures that D t − 1 c o = 1 for all t. We can also use deterministic …
