How to reach older versions help pages?

For example I am using 2013b, and mnrfit example from the help page (2016) is not working for me: load fisheriris; sp = categorical(species); [B,dev,stats] = mnrfit(meas,sp);

On the right hand side of the documentation home page there's an "Other Releases" hyperlink:

http://www.mathworks.com/help/index.html

http://www.mathworks.com/help/doc-archives.html

Documentation consistent with the release of MATLAB and other products you're using should have been installed when you installed the products for that release. Open up that installed documentation using the doc function.

To configure MATLAB to use the local documentation, see: https://www.mathworks.com/matlabcentral/answers/1936264-how-can-i-configure-matlab-to-use-the-local-offline-documentation-instead-of-the-online-documentatio
