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.
In the US, the entire hybrid system (which includes the hybrid battery pack) is warrantied for 8 years/100,000 miles. If you are in a California-emission state, the hybrid battery pack in a 2004-2009 Prius is further covered under the CA emissions warranty for 10 years/150,000 miles.
