Now the problem has become one of finding the nearest point on this plane to the origin, and its distance from the origin. The point on the plane in terms of the original coordinates can be found from this point using the above relationships between and , between and , and between and ; the distance in terms of the original coordinates is the ...
In statistics, probability theory, and information theory, a statistical distance quantifies the distance between two statistical objects, which can be two random variables, or two probability distributions or samples, or the distance can be between an individual sample point and a population or a wider sample of points. A distance between ...
where d ij is the Euclidean distance between the i th and j th points in a data set of n points, t is the search radius, λ is the average density of points (generally estimated as n/A, where A is the area of the region containing all points) and I is the indicator function (i.e. 1 if its operand is true, 0 otherwise).

Detection probability decreases with distance from center line (y = 0). The drop-off of detectability with increasing distance from the transect line is modeled using a detection function g(y) (here y is distance from the line). This function is fitted to the distribution of detection ranges represented as a probability density function (PDF).
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...
The distance from a point to a plane in three-dimensional Euclidean space [8] The distance between two lines in three-dimensional Euclidean space [9] The distance from a point to a curve can be used to define its parallel curve, another curve all of whose points have the same distance to the given curve. [10]
Total variation distance is half the absolute area between the two curves: Half the shaded area above. In probability theory , the total variation distance is a statistical distance between probability distributions , and is sometimes called the statistical distance , statistical difference or variational distance .
In the 2D plane, pick a fixed point at distance ν from the origin. Generate a distribution of 2D points centered around that point, where the x and y coordinates are chosen independently from a Gaussian distribution with standard deviation σ (blue region). If R is the distance from these points to the origin, then R has a Rice distribution.
