Usually, the order of integration is either I(0) or I(1); It's rare to see values for d that are 2 or more. So, what exactly is an I(0) process? An I(0) process ...

Orders of Integration Terminology. – A series with a unit root (a random walk) is said to be integrated of order one, or I(1).

In statistics, the order of integration, denoted I(d), of a time series is a summary statistic, which reports the minimum number of differences required to ...
