Definition
Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)
- A measure of the degree to which a data matrix is decisive. Data decisiveness is calculated as the ratio of (S - S) to (S - M), where S is the observed length of the most parsimonious cladogram, S is the mean length of all possible bifurcating cladograms and M is minimum possible length of a cladogram were there no homoplasy in the data.
- S is S with overline.
