The NATO Stock Number or National Stock Number (NSN) is a 13-digit alphanumeric code consisting of a Group of Supply, a Class of Supply and the unique NIIN to designate unique items of supply grouped by their relative catalog category. The first four digits are the NATO Supply Classification (NSC) or Federal Supply Class (FSC) code.
This is usually achieved at least in part by having at least two layers of insulating material between live parts and the user, or by using reinforced insulation. In Europe, a double insulated appliance must be labelled Class II or double insulated or bear the double insulation symbol: ⧈ (a square inside another square). As such, the ...

Early work on statistical classification was undertaken by Fisher, [1] [2] in the context of two-group problems, leading to Fisher's linear discriminant function as the rule for assigning a group to a new observation. [3] This early work assumed that data-values within each of the two groups had a multivariate normal distribution.
Statistical properties of items can be expressed with greater precision which increases the interpretation accuracy of DIF between two groups. These statistical properties of items can be expressed graphically, improving interpretability and understanding of how items function differently between groups.
