Figure 2.3. Basic matrices used in analysis of a focal species in relation to its habitat. Presence, abundance, or other measure of performance of the focal species in each sample unit is in matrix F. The p habitat variables for each sample unit are in H. The matrix X summarizes the habitat variables along q synthetic gradients (such as ordination axes) or habitat classes. See Table 2.7 for further explanation.
