CASE STUDIES IN BIOMETRY: Chapter 11. Time-Series Analyses of Beaver Body Temperatures Penny S. Reynolds The file ch11b.dat contains a body temperature time series for a subadult female beaver (Castor canadensis). Observations were made at Sandhill Wildlife Area, Wisconsin, November 3-4, 1990 (before freeze-up). Temperature observations follow a plateau pattern, typically observed during the entire ice-free period (late spring to late autumn). Only the first 100 observations are included in this data set. Variable list: Observation number Julian day Time Body temperature (degrees C) Activity (0 = animal inside retreat; 1 = animal outside retreat)
