The pair consisting of a point of the point process and its corresponding mark is called a marked point, and all the marked points form a marked point process. It is often assumed that the random marks are independent of each other and identically distributed, yet the mark of a point can still depend on the … Meer weergeven In probability, statistics and related fields, a Poisson point process is a type of random mathematical object that consists of points randomly located on a mathematical space with the essential feature that the points occur … Meer weergeven If a Poisson point process has a parameter of the form $${\textstyle \Lambda =\nu \lambda }$$, where $${\textstyle \nu }$$ is Lebesgue measure (that is, it assigns length, area, or volume to sets) and $${\textstyle \lambda }$$ is a constant, … Meer weergeven Simulating a Poisson point process on a computer is usually done in a bounded region of space, known as a simulation window, and requires two steps: appropriately creating a random number of points and then suitably placing the points in a random … Meer weergeven Depending on the setting, the process has several equivalent definitions as well as definitions of varying generality owing to its many applications and characterizations.
