Trade-Off between Sampling Frequency and Duration and Their Influences on the Estimation of Space Use of Japanese Macaques

Figure 1

Conceptual diagram showing errors of omission and commission in relation to the reference and predicted areas. The black and gray circles represent the reference and predicted areas, respectively. True: an estimator for space use correctly predicted the actual status of a location (inside or outside the area), and false: the estimator incorrectly predicted the status. Positive: the status of the location was predicted to be inside the area, and negative: it was predicted to be outside the area. False negatives and false positive are regarded as errors of the estimator. Errors of omission are the locations which are incorrectly predicted as “outside the area” (i.e., false negatives; underestimations). Errors of commission are the locations which are incorrectly predicted as “inside the area” (i.e., false positives; overestimations).
