Reducing or Increasing flow rate without temperature change.

If i have water at 90 C, (pressure 16 bar) with a flow rate of 80 kg/s and i need to reduce the flow rate to 20 kg/s before running it through a heat exchanger, can i achieve that with a flow...

Pre-conditions for panel cointegration analysis?

while conduction panel data analysis, the outcome of unit root tests says that some of the variables are already stationary at level while other are non-stationary at level, but after first...

How to conduct CUSUM and CUSUMsq test after the inclusion of an exogenous dummy variable in my ARDL model?

Hi all, I have been struggling a great deal with this matter and as such I hope you could provide me with answer. I have added a dummy variable to my ARDL model to improve its stability (Eviews)....

If different variables are stationary at different levels I(0), I(1), and I(2), and are cointegrated, can I run my data by using VECM ?

My data are consisted of 3 exogenous variables (TFIN, SR, and INF), and 1 endogenous variable (GDP). TFIN and INF are stationary at I(0), GDP is stationary at I(1), and SR is stationary at I(2). I...

How do I correct the non-stability of my var model?

Hi, I carried out an analysis using the VAR (VECM) framework. My variables are integrated of order 1 and are cointegrated (based on the result of the trace statistic and maximum eigenvalue),...

What is more important for a proper cointegration analysis: taking into account structural breaks or having sufficient observations?

To clarify, I have several time series of roughly 30 years with monthly datapoints. Given the fact that the time series are quite volatile, I expected more than 2 structural breaks and conducted...

Is it possible (panel or time series) cointegration including one lagged variable?

Dear all, I am certain that one of the variables in my vector can affect the rest only if it is lagged. For example, lets imagine an agriculture product which is planted in a year and harvest in...

Hi all, can OLS be used on single equation when it has two (2) cointegrating vectors?

Let suppose an equation Yt = a + b1Xt + b2Zt + b3Ft + e where Y is the dependent variable and X, Z and F are independent variable. If johansan cointegration shows 2 cointegrating vectors then...

How to deal a random walk model with a drift?

I'm regressing households' spending (PCE) on disposable income (PDI) between 1980 and 2018 for the U.S economy. I noticed that the coefficient of PDI is higher than 1. I first think that coeff. of...
