A simple AR(1) model is where is the variable of interest, is the time index, is a coefficient, and is the error term (assumed to be white noise). A unit root is present if . The model would be non-stationary in this case. The regression model can be written as where is the first difference operator and . This model can be estimated and testing for a unit root is WebThis means that we can simply calculate a t-statistic and compare it to the critical values of a Dickey-Fuller table.
