WebTesting for Mean Reversion. A continuous mean-reverting time series can be represented by an Ornstein-Uhlenbeck stochastic differential equation: d x t = θ ( μ − x t) d t + σ d W t. Where θ is the rate of reversion to the mean, μ is the mean value of the process, σ is the variance of the process and W t is a Wiener Process or Brownian ... WebIn the case of serial correlation, IPS propose using the ADF t-test for individual series. However, E(ti,T) and V(ti,T) will vary as the lag length included in the ADF regression varies. They tabulate E(ti,T) and V(ti,T) for different lag lengths.

WebRDF = ADF * Q† (9a) Note the factor Q† should reflect the corrected RDF value. Of course the original definitions of RDF (and thus equation 9a) did not account for the ‘[1 / (1 – .005161 * RE)]’ correction term. It was noted that Balling first pro-posed calculating the ratio of RDF/ADF20 and it is termed ‘Balling’s shorter formula’.
