How Errors are Calculated

[Owen Arnold]

An important question raised more than once at the ILL was about how errors are calculated and carried through, the plus algorithm documentation http://www.mantidproject.org/Plus has a broken link for this and in the new documentation, this concept is completely missing.

This is an important point for people to trust Mantid, to know what it does about the errors.

I hadn't seen that this had gone to Anders, returning it.

Concept wiki page http://www.mantidproject.org/Error_Propagation created. First version of this was done by one week work experience student Sandy Steele

[Owen Arnold]

Good documentation above. We at least need to link to this documentation from the rst files so that people looking at the plus algorithm will know how it behaves. Nick Draper is working on some concept rst pages, so I think the contents of this document should go into there, and then we can make good links from each algorithm page to the Errors rst page.

To tester:

PLEASE NOTE THAT THERE IS NO BRANCH TO MERGE WITH THIS TICKET. THE CHANGES WAS COMMITTED TO A BRANCH THAT HAS BEEN MERGED WITH MASTER. (it was done this way since updates to this error probagation page happened halfway through Nick translating of all the concept pages)

1. check that e.g. Minus (and Plus), ​http://docs.mantidproject.org/nightly/algorithms/Minus-v1.html algorithm have link to 'Error propagation' concept page

2. check the content of the error propagation page

[Alex Buts]

Good and timely work but the explanation on error propagation in Rebin, Remove background and ConvertMDHistoToMatirix works algorithms needs to be explicitly added to the description (I suspect surprises there)

Ticket #10127 has been created for that.
