Wiener index calculator

The wiener index W (G) of a connected graph G is the sum of the distances between all pairs of vertices of G. In this paper, we give theoretical results for Calculation of Wiener index is usually done using distance matrix. For any matrix calculation smaller the matrix, better and fast are the computations. This paper Question: How do we measure diversity? Variables: H, Shannon's diversity index. S, total number of species in the community (richness). p The investment calculator allows you to determine the current value of your investment at a specific date in the past.

Shannon-Wiener Diversity Index. Shannon-Wiener Diversity Index is a term in biology/ecology. It measures the rarity and commonness of species in a community. The calculator uses the following formula to calculate the Shannon-Wiener diversity index: H = - S p i ln ( p i) . Here p i is the proportion of total number of species made up of the ith species.
