WebFeb 1, 2011 · An important step toward our recent understanding of nestedness was the introduction of the matrix temperature concept and its associated metric T as well as its companion software ( Nestedness Temperature Calculator) by Atmar and Patterson (1993). WebThe most popular nestedness calculator is the ‘‘temperature of randomly but present a number of non-trivial structural traits such Atmar and Patterson (used to extract a temperature from the as the small-world property, scale freeness, hierarchical organiza- matrices in Fig. 1) [8].
WebJun 15, 2024 · On the other hand, algorithms that seek to maximize nestedness (like those used to minimize nestedness temperature [22], [70], [73]) cannot be used to evaluate the level of nestedness by a specific node-level property; however, one can compare the resulting maximal nestedness with the degree of nestedness by a property of interest … WebIn principle nestedness temperature is calculated by using a line of perfect order (using a genetic algorithm) to determine the reordering of rows and columns that leads to …
WebJun 7, 2010 · Importantly, there is a significant positive correlation between the tendency to detect significant nestedness, as measured by the z-score, for the metric based on nestedness temperature and the analytic measure for the two null models (r=0·930, P<0·001 and r=0·747, P<0·001 respectively).
