pottery information equivalent


A statistical package that may be used to compare quantified assemblages of broken and incomplete objects, such as ceramics, glass and bones. Pie-Slice uses Estimated Vessel Equivalent (EVE) as a base form of measurement, in which each measurable fraction is scored as a fraction of a complete vessel. It also trials the use of a new statistical transformation - the pseudo-count transformation - which converts EVEs into Pottery Information Equivalents (PIEs). The latter enables assemblages to be compared using techniques such as log-linear and correspondence analyses.
