In the mathematical discipline of graph theory, the line graph of an undirected graph G is another graph L(G) that represents the adjacencies between edges of G. L(G) is constructed in the following way: for each edge in G, make a vertex in L(G); for every two edges in G that have a vertex in common, make an edge between their corresponding vertices in L(G).
An undirected graph with three vertices and three edges. In one restricted but very common sense of the term, [1] [2] a graph is an ordered pair = (,) comprising: , a set of vertices (also called nodes or points);
In mathematics, the term linear function refers to two distinct but related notions: [1]. In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. [2]
The general linear model and the generalized linear model (GLM) [2] [3] are two commonly used families of statistical methods to relate some number of continuous and/or categorical predictors to a single outcome variable.
An example of a linear time series model is an autoregressive moving average model.Here the model for values {} in a time series can be written in the form = + + = + =. where again the quantities are random variables representing innovations which are new random effects that appear at a certain time but also affect values of at later times.
In statistics, a generalized linear model (GLM) is a flexible generalization of ordinary linear regression.The GLM generalizes linear regression by allowing the linear model to be related to the response variable via a link function and by allowing the magnitude of the variance of each measurement to be a function of its predicted value.
If They Tell You I Fell (Spanish: Si te dicen que caí) is a 1989 Spanish film written and directed by Vicente Aranda, starring Victoria Abril and Jorge Sanz along with Antonio Banderas and Javier Gurruchaga. It is an adaptation of the novel of the same title by Juan Marsé, which was based on the killing of Carmen Broto. [1]
Linear languages are closed under union.Construction is the same as the construction for the union of context-free languages. Let , be two linear languages, then is constructed by a linear grammar with |, and , playing the role of the linear grammars for ,.
