• Spatial ecology — is a specialization of ecology and geography that is concerned with the identification of spatial patterns and their relationships to ecological events. In spatial ecology, ecological events can be explained through the detection of patterns at a …   Wikipedia

• Value-added theory — (also known as social strain theory) was first proposed by Neil Smelser and is based on the assumption that certain conditions are needed for the development of a social movement. [Kenall 2005] Smelser saw social movements as side effects of… …   Wikipedia

• Spatial dependence — In mathematical statistics, spatial dependence is a measure for the degree of associative dependence between independently measured values in a temporally or in situ ordered set, determined in samples selected at positions with different… …   Wikipedia

• Spatial analysis — In statistics, spatial analysis or spatial statistics includes any of the formal techniques which study entities using their topological, geometric, or geographic properties. The phrase properly refers to a variety of techniques, many still in… …   Wikipedia

• Complete spatial randomness — (CSR) describes a point process whereby point events occur within a given study area in a completely random fashion. Such a process is often modeled using only one parameter, i.e. the density of points, ρ within the defined area. This is also… …   Wikipedia

• Singular value decomposition — Visualization of the SVD of a 2 dimensional, real shearing matrix M. First, we see the unit disc in blue together with the two canonical unit vectors. We then see the action of M, which distorts the disk to an ellipse. The SVD decomposes M into… …   Wikipedia

• P-value — In statistical significance testing, the p value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. One often rejects the null hypothesis when the …   Wikipedia
