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.
Under California emissions laws, the Chevy Voltâs battery pack is regulated to have warranty coverage up to 100,000 miles. But the Leaf is a zero emission vehicle, and therefore is not subject to the same oversight. (Yet, we anticipate the Nissan will at least match competitors for warranty.)
