  2. Spatial variability - Wikipedia

    en.wikipedia.org/wiki/Spatial_variability

    Spatial variability can be assessed using spatial descriptive statistics such as the range. Let us suppose that the Rev' z(x) is perfectly known at any point x within the field under study. Then the uncertainty about z(x) is reduced to zero, whereas its spatial variability still exists. Uncertainty is closely related to the amount of spatial ...

  3. Variogram - Wikipedia

    en.wikipedia.org/wiki/Variogram

    The empirical variogram is used in geostatistics as a first estimate of the variogram model needed for spatial interpolation by kriging. Empirical variograms for the spatiotemporal variability of column-averaged carbon dioxide was used to determine coincidence criteria for satellite and ground-based measurements. [4]

    In addition to spatial data editing and visualization, ArcGIS provides spatial analysis and modeling features including overlay, surface, proximity, suitability, and network analysis, as well as interpolation analysis and other geostatistical modeling techniques. Python, Web API, .NET: Proprietary. Analytical extensions can be purchased separately.

  6. Glossary of experimental design - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_experimental...

    Analysis of variance (ANOVA): A mathematical process for separating the variability of a group of observations into assignable causes and setting up various significance tests. Balanced design: An experimental design where all cells (i.e. treatment combinations) have the same number of observations.

  7. Generalized additive model for location, scale and shape

    en.wikipedia.org/wiki/Generalized_additive_model...

    The generalized additive model for location, scale and shape (GAMLSS) is a semiparametric regression model in which a parametric statistical distribution is assumed for the response (target) variable but the parameters of this distribution can vary according to explanatory variables.

  8. Spectral variability hypothesis - Wikipedia

    en.wikipedia.org/wiki/Spectral_variability...

    The Spectral Variability Hypothesis (SVH) states that spatial variability in the reflectance of vegetated surfaces relates to plant species richness.It has been originally coined by Palmer et al. (2000) and states that "species richness will be positively related to any objective measure (e.g. standard deviation) of the variation in the spectral characteristics of a remotely sensed image". [1]

  9. Data and information visualization - Wikipedia

    en.wikipedia.org/wiki/Data_and_information...

    Represents one categorical variable which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area), is proportional to the quantity it represents. For example, as shown in the graph to the right, the proportion of English native speakers worldwide; Line ...
