Statistical Analysis

As the field of environmental problem solving has matured, statistical approaches have become more fully integrated into a variety of decision types, including sampling, risk assessment, and trend analysis. This page presents a diverse group of DSTs that help the user solve a variety of common problems in environmental investigation and remediation; however, each of these tools exemplifies how a DST can support a decision or action by providing a statistical underpinning to the decision-making process.

1 ERPIMS data can be imported through an Access file or a series of text files (.tes, .res, .sam, .ldi).
2 GeoSEM uses several GIS vector and raster file formats: DOD vector product format (VPF) , ESRI product files, CAD drawings (dxf), ASCI II grids, and georeferenced image formats such as geoTIFs, bitmaps, GIFs, JPGs, and ERDAS.
