Integrated of order one
If two or more series are individually integrated (in the time series sense) but some linear combination of them has a lower order of integration, then the series are said to be cointegrated. A common example is where the individual series are first-order integrated () but some (cointegrating) vector of coefficients exists to form a stationary linear combination of them. For instance, a stock market index and the price of its associated futures contract move through time, … NettetWhether you are using one of our services or a fully integrated solution, IDS is dedicated to improving your operational efficiencies, enhancing your service and ultimately improving your bottom ...

Nettet1 More generally, a set of variables is cointegrated of order (d,b) if each variable individually is integrated of order d, but at least one linear combination exists which is of order (d-b). Most of the literature focuses on the case d—l, b—l and we will do the same here. 2 This definition follows Engle and Grsnger [1987]. Much of the

When plotting the data, we can see that it has some up/down movements but is overall clearly trending upwards.

A random walk can be written as y t = y t − 1 + ε t as you have done it. The increments ε t have to be independent of each other over time, e.g. ε t …
