An estimate of the risk or prevalence ratio, adjusted for confounders, can be obtained from a log binomial model (binomial errors, log link) fitted to binary outcome data. We propose a modification of the log binomial model to obtain relative risk estimates for nominal outcomes with more than two attributes (the log multinomial model).
The batteries are not dealership's and the warranty is not theirs. Both belong to the manufacturer of the battery who makes them and Toyota just uses them and the battery manufacturer does not offer free alignments, just battery replacements. Last edited: Aug 28, 2014.
If the battery pack in your Toyota Prius dies before the end of its 150,000 (or 100,000) mile warranty, Toyota will replace it free of charge. But if your car is out of warranty, you join the 500 or so owners every month experiencing an expired nickel-metal-hydride battery pack.
