Correspondence analysis - a statistical method of displaying trends in cross-tabulated data in two dimensions for visual display.
EVEse - a means of pottery quantification calculated by finding part of a pot that can be measured as a fraction of some whole, usually by measuring rim sherds. These percentages are totalled to give the number of estimated vessels in an assemblage.
Inertia - a measure of the variability described by each axis in correspondence analysis
Mansio - an official road-side settlement for the accommodation of travellers
Mortaria - a Roman pottery form with steep sides inset with angular inclusions, presumably used in the preparation of specific dishes. Not indigenous to Britain.
