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.
With that said, Toyotaâs hybrid batteries and all other hybrid specific parts normally have a warranty of eight years or 100,000 miles. In California, the warranty is 150,000 miles. Moreover, there are numerous reports of the Prius being driven over 200,000 miles on the original battery.
