@@CrunchEconometrix Thank you for your reply. I have data where my dependent variable and independent variables (variable of interest and controls) are stationary, BUT they are autocorrelated. I have read that stationary I(0) time series can not be cointegrated so I am hesitant with my model selection. Do you think that for stationary data, that is autocorrelated an ARDL model is appropriate? I assume that for that kind of data, only the short-term coefficients are interpretable because bounds testing does not make sense with stationary data, right? Or should I consider a VAR model and add controls as exogenous variables? Thank you for the help. Best regards

@@CrunchEconometrix I use the terms "serial correlation" and "autocorrelation" interchangeably. I am not concerned if my variables are Pearson correlated or not as long as there is no multicollinearity (there is not). I am looking for a model that is appropriate for stationary variables but can account for autocorrelation. If I used OLS regression, I would run into endogeneity issues due to correlated error terms. I wanted to use ARDL model, but that is not typically used for stationary variables because it is used for long run relationships. In Pesaran, Shin, SMith (2001) they write that. "Two degenerate cases arise. ... Yt is (trend) stationary or yt ¾ I0 whatever the value of r". So I am unsure if using ARDL, and doing bounds testing and such even makes sense (note that my dependent variable, is DCC correlation which is by definition bounded by (-1, 1). What I am asking is if it is better to use a VAR model or do the ARDL model but only estimate the short run coefficients. I hope this makes sense, if I am mistaken, please correct me. I really appreciate any help. Thank you

Thank you for your contributions to econometrics. When I estimate the model with EKKY and look at the diagnostic tests, I encounter the autocorrelation problem. I tried autoregressive models to solve this. The problem persists. Will it help if I try it with GLS/GLM? In the final stage, I will perform diagnostic tests again. There is no heteroscedasticity problem in your application, but the coefficients are statistically insignificant. Why did you ignore the coefficients? I wanted to learn this. Thanks, Kind regards.

Are the t-statistics for ARMA coefficients adjusted for the bias of the estimator? there is no really a good way to estimate ARMA coefficients bias free like in a regular regression setting. if not, they are wrong even in large samples as the bias is very persistent and consistency kicks in in the limit.

For example, if my data is daily, does "10 periods" mean 10 days? I have another question: in the case where the impulse response is not clear, how do we interpret the results? For example, if we observe a decrease in the first few periods (1 to 2), followed by an increase (3 to 5) before fading away in the 6th period, how do we determine if the overall impact is positive or negative?

I have a panel and a have to estimate a set of regressions out of it, I have carried out the hausman test and the conslusion I got is that I have to employ fixed effects, however, I have a long panel data with heteroscedasticity and autocorrelation, then one of the alternatives I have found for this issue is estimating a PSCE model, I have already done the cross sectional dependence test and this model is still the best option. My question is: For controling the unobserved characteristics that might vary across units (which in my case are developing countries) is it necessary to include country dummies?
