Spatial Statistics in archeoViz
archeoViz
includes some spatial analysis functionalities for basic and exploratory use:
- computation of 3D regression surfaces (summarising the distribution of the objects by layer),
- computation of 3D convex hulls (showing the maximal extension of the objects by layer),
- computation of 2D contour lines (in the “Map” tab), summarising the horizontal distribution of the objects, in general or by layer.
Analysis with Third-party Applications
Data can be export from the “Statistics” tab to third-party applications for other analysis. If applicable to the dataset at hand, links to the following applications are displayed in the archeoViz “Statistics” tab:
- archeofrag, for refitting analysis
- seriograph, for seriation
- explor, for correspondence analysis
- amado online, for seriation and classification
- shinyHeatmaply for classification and heatmaps
See for example the Shuidonggou 2 archeoViz instance, where data can be exported to these applications.
Export to archeofrag
The TSAR method (“Topological Study of Archaeological Refitting”) was published as a new approach in refitting analysis. This method is implemented in the archeofrag R package. This package is complemented by the archeofrag.gui R package, offering a convenient graphical user interface. If a dataset with refitting data is loaded in archeoViz it can be transmitted to an archeofrag.gui instance online. See, for example, the Grotte XVI or Flageolet archeoViz instances.
Export to the Seriograph
The Seriograph is a web application (part of the SPARTAAS collection) to visualise changes in the quantitative distribution of artefacts types in ordered or unordered series of spatial units. See, for example, the Poeymaü and Flageolet archeoViz instances.
Export to explor (correspondence analysis)
Data can be exported to the explor R package / shiny application, which has been adapted and deployed for archeoViz. Explor performs a correspondence analysis and allows to interactively explore the results. See, for example, the Taï, Poeymaü or Pirro Nord archeoViz instances.
Export to AMADO online (seriation and classification)
AMADO online is an application for seriation and classification of count data. The application interface is multilingual (9 languages). See, for example, the Taï, Poeymaü or Pirro Nord archeoViz instances.
Export to shinyHeatmaply
Heatmaply is an R package to generate interactive heatmaps. shinyHeatmaply is a Shiny web application to use heatmaply’s functionalities online, namely to compute a clustering using various distances and clustering methods, and to display the result as an heatmap. See, for example, the Grande Rivoire or Poeymaü archeoViz instances.
