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.
The battery pack in the Toyota Prius is guaranteed for 100,000 miles. Honda and Ford stand behind theirs for 80,000 miles. It's safe to say that replacement is a rare event. If you're faced with replacing the battery on an out-of-warranty car, there's no need to panic. The cost of a new battery pack continues to decline and now stands at about $3,000, not bad when you consider how long they last. A used pack salvaged from a wrecked vehicle will set you back around $1,000. Battery replacement should be left to professionals.
