Notes. Values correspond to the posterior sample mean, with errors being the standard deviation of the MCMC samples. In the second line we report the 95% highest density interval (HDI). Only parameters common to all models are tabulated.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
