WebbIn a slightly different formulation suited to the use of log-likelihoods (see Wilks' theorem), the test statistic is twice the difference in log-likelihoods and the probability distribution of the test statistic is approximately a chi-squared distribution with degrees-of-freedom (df) equal to the difference in df's between the two models (therefore, the e −2 likelihood … Webbf α ( v 1, v 2) - f statistic that has a cumulative probability equal to 1 − α and v 1 and v 2 degrees of freedom.
