		A table of plus and minus signs can be used to determine the sign on each run for a particular contrast.The column headings for the table are the main effects A and B, in the AB interaction, and I, which represents the total.
		Signs for the main effects (columns A,B, and C) are obtained by associating a plus with the high level.
		Once the signs for the main effects have been established, the sighs for the remaining columns are found by multiplying the appropriate preceding columns, row by row.

	Plus-minus sign - Wikipedia, the free encyclopedia
		The plus-minus sign (±) is a mathematical symbol commonly used to indicate the precision of an approximation, or as a convenient shorthand for a quantity which has two possible values opposite in sign.
		The use of ± for an approximation is most commonly encountered for presenting the numerical value of a quantity together with its tolerance or statistical margin of error.
		This mild abuse of notation is meant to indicate that the sign of the terms alternate, where (starting the count at 0) the terms with an even index n are added while those with an odd index are subtracted.

		That is, the signs of these terms may be taken as the top sign in one transformation and the bottom sign in another transformation, while the terms preceded by "+" or "-" signs remain fixed.
		Therefore, these signs might, more properly, be called plus and minus, rather than plus or minus signs, until one or the other sign is specified.
		However, even though both of these signs (plus and minus, and minus and plus) are combinations of both plus and minus, they retain their opposite nature.

	MATHEWS: Steinhaus Triangles
		Continue by adding lines with n-1, n-2,..., 1 signs such that below a pair of equal signs a plus sign is drawn and below a pair of unequal signs a minus sign is drawn.
		It's easy to see that the minimal number of minus signs is zero (corresponding to the triangle existing entirely of +'s) and that the average number of minus signs is exactly N/2 where N=n(n+1)/2 denotes the total number of signs in the triangle.
		Each of the small triangles has at most 2 minus signs showing that the maximal number of minus signs is ≤ [(n(n+1)+1)/3] = [(2N+1)/3] where [x] is the greatest integer not exceeding x.

		Since there are 2 and 3 plus and minus signs, respectively, in this circle KNN will assign a minus sign to the outcome of the query point.
