Notes. Themaximum likelihood solution (Max(Like)), the median (Med), mode (Mod) and standard deviation (Std) of the posterior distribution for each parameter is provided, as well as the 68.3 % (CI(15.85),CI(84.15)) and 95.45 %(CI(2.275),CI(97.725)) confidence intervals. The prior for each parameter can be of type: : uniform, : normal, : split normal, : truncated normal.

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.
