  3. 1. Data • http://kdd.ics.uci.edu/ - Cover Type The forest cover type for 30 x 30 meter cells obtained from US Forest Service (USFS) Region 2 Resource Information System (RIS) data. • Data Characteristics The actual forest cover type for a given observation (30 x 30 meter cell) was determined from US Forest Service (USFS) Region 2 Resource Information System (RIS) data. Independent variables were derived from data originally obtained from US Geological Survey (USGS) and USFS data. Data is in raw form (not scaled) and contains binary (0 or 1) columns of data for qualitative independent variables (wilderness areas and soil types). • Summary Statistics Number of instances (observations) 9999 Number of Attributes 54 Attribute breakdown • 12 measures, but 54 columns of data (10 quantitative variables, 4 binary wilderness areas and 40 binary soil type variables) Missing Attribute Values None

  4. 1. Data • Variable Information

  5. 1. Data • Code Designations <Wilderness Areas> 1 -- Rawah Wilderness Area 2 -- Neota Wilderness Area 3 -- Comanche Peak Wilderness Area 4 -- Cache la Poudre Wilderness Area <Soil Types> 1 to 40 : based on the USFS Ecological Landtype Units for this study area. <Forest Cover Types> 1 -- Spruce/Fir 2 -- Lodgepole Pine 3 -- Ponderosa Pine 4 -- Cottonwood/Willow 5 -- Aspen 6 -- Douglas-fir 7 -- Krummholz

  6. 1. Data • Class Distribution Number of records of Spruce-Fir: 1375 Number of records of Lodgepole Pine: 1462 Number of records of Ponderosa Pine: 1262 Number of records of Cottonwood/Willow: 1620 Number of records of Aspen: 1582 Number of records of Douglas-fir: 1349 Number of records of Krummholz: 1349 Number of records of other: 0 Total records: 9999
