Corrections

Thanks to readers who have pointed out errors!

• An earlier version of the book claimed that the anova() function would not compute F-statistics and p-values when given non-nested models to compare. Kaitlyn Cook pointed out that this is incorrect; anova() is happy to produce F-statistics and p-values from a non-nested model comparison, so long as the smaller model is a worse fit to the data than the larger model! Thank you Kaitlyn, and shame on you anova().
