Palisade vegetation alongside as this allows criminals to make an unseen breach. Palisade A palisade—sometimes called a stakewall or a paling—is typically a fence or wall made from wooden stakes or tree trunks and used as a defensive structure or enclosure. Palisade derives from "pale", from the Latin word "", meaning stake, specifically a stake used to support a fence. A palisade gangs these side by side to create a fence entirely made of pales. Typical construction consisted of small or mid-sized tree trunks aligned vertically, with no free space in between. The trunks were sharpened or pointed at the top,
Distance from a point to a line a graph, etc. In Deming regression, a type of linear curve fitting, if the dependent and independent variables have equal variance this results in orthogonal regression in which the degree of imperfection of the fit is measured for each data point as the perpendicular distance of the point from the regression line. In the case of a line in the plane given by the equation where "a", "b" and "c" are real constants with "a" and "b" not both zero, the distance from the line to a point ("x","y") is The point on this line which is closest to ("x","y")
