Summary Discovering Statistics Using IBM SPSS Statistics −2LL - the log-likelihood multiplied by minus 2. This version of the likelihood is used in logistic regression. α-level - the probability of making a Type I error (usually this value is 0.05). Adjusted mean - in the context of analysis of covariance this is the value of the group mean adjusted for the effect of the covariate. Adjusted predicted value - a measure of the influence of a particular case of data. It is the pred...
