which statement describes the use of ecm for a time series equation can you use cdms multiple times what is the function of vector error correction (eco) time series econometrics how to assess the endogeneity of left hand variables how to evaluate if the t statistic on the different ecm coefficients yields different (conflicting) results? when do we use vector error correction in the ecm model how to assess the endogeneity of the left hand variable if t-stats on different ecm coefficients yield different (conflicting) results when using a model with more than one coefficient of cointegration what is ecm model how does ecm affect endogeneity can you use multiple ecm terms why use vector error correction in time series econ modeling how to assess endogeneity of right hand variables if t-stats on different ecm coefficients yield different (conflicting) results? vecm multiple cointegration vectors when does vector error correction occur which ecm term can be used with multiple cointegration vectors? do ecm terms have to be negative which model is used to assess endogeneity of left hand variables if the coefficients of the ecm are negative? quizlet how many cointegration vectors for ecm what is ecm ecm
