WebJul 14, 2024 · As we saw in Chapter 14, the F-test is constructed from two kinds of quantity: sums of squares (SS) and degrees of freedom (df). These two things define a mean square value (MS = SS/df), and we obtain our F statistic by contrasting the MS value associated with “the thing we’re interested in” (the model) with the MS value associated with ... WebNov 29, 2024 · Akaike information criterion ( AIC) is a single number score that can be used to determine which of multiple models is most likely to be the best model for a given data set. It estimates models relatively, meaning that AIC scores are only useful in comparison with other AIC scores for the same data set. A lower AIC score is better.
