Statistical Analysis and Third-party Applications in the archeoViz Application for Spatial Archaeological Data

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, and partially demonstrated in the archeofrag R Shiny web application. If a dataset with refitting data is loaded in archeoViz it can be transmitted to the online archeofrag application. 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.
