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.
Batteries and Tires are rarely covered under the manufacturer warranty. I worked in the business for many years on the service and fixed operations side, including with Ford (Canada). They have their own warranties provided by the manufacturer. I would go with the dealer on this one.
