How to Perform a Cointegration Test in EViews: A Step-by-Step Guide

- by Nathan Robinson

In time series econometrics, cointegration is a critical concept. It establishes a long-run equilibrium relationship between two or more non-stationary time series variables, meaning that even if they drift apart in the short run, they will eventually move back toward a shared, stable relationship.

EViews, a popular statistical software package, provides powerful tools, primarily the Johansen Cointegration Test, to detect this relationship. This guide walks you through the necessary pre-tests and the steps for performing the test in EViews.

Phase 1: Pre-Testing—Checking for Unit Roots

Before you can test for cointegration, you must confirm that all your variables are non-stationary and are integrated of the same order, typically I(1) (stationary after one difference). If the variables are stationary at their levels (I(0)), you do not need a cointegration test; you can proceed directly with standard Ordinary Least Squares (OLS) regression.

Why Outsource Dental Payment Management for Your Practice?

- by Nathan Robinson

It is important to remember that running a successful dental practice is not just about dentistry and other things that go with it. Instead, you should think about the entire mechanism and be aware of each moving part that requires experience and skill to ensure overall success.

For instance, dental billing processes are the essential aspects that you should handle to prevent potential issues from happening. We are talking about insurance codes and claims that are more complex than oral surgeries, which is why you need an in-house expert in numbers. As soon as you check here, you will understand the importance of oral health.

However, you can also outsource a third-party company who will help you handle each procedure. That way, you can prevent the potential expenses of hiring an in-house expert while dealing with billing and payment management.
