Abstract Cladistic data are more decisive when the possible trees differ more in tree length. When all the possible dichotomous trees have the same length, no one tree is better supported than the others, and the data are completely undecisive. From a rule for recursively generating undecisive matrices for different numbers of taxa, formulas to calculate consistency, rescaled consistency and retention indices in undecisive matrices are derived. The least decisive matrices are not the matrices… 
RANDOM DATA, HOMOPLASY AND INFORMATION
TLDR
The relationship between homoplasy and the degree to which a data set provides information to choose among the possible trees is analysed, and a statistic, Data Decisiveness, DD is proposed to measure decisiveness.
Assessing progress in systematics with continuous jackknife function analysis.
TLDR
Convergence of data on a reference tree does not guarantee historical accuracy, but it does predict that the accumulation of further data under the sampling model will not lead to rapid changes in the hypothesis.
Phylogenetic Noise Leads to Unbalanced Cladistic Tree Reconstructions
?Cladistic tree balance is the extent to which internal nodes on a cladistic tree define clades of equal size. More robust maximum-parsimony trees taken from the literature are more balanced.
Unambiguous Data or Unambiguous Results?
Consider data matrix A, with 25 taxa (including dummy outgroup) and 34 characters (taken from Hovenkamp, 1996). When this matrix is analyzed with Hennig86 (Farris, 1988; characters ordered, using mh;
RANDOM CLADISTICS
The paper by Faith and Cranston (1991) is but the latest manifestation ofa disturbing phenomenon in cladistics. In their paper, as well as in Archie ( 1989) and Faith ( I99 1) ~ randomizations of
THE RELATIONSHIP BETWEEN HOMOPLASY AND CONFIDENCE IN A PHYLOGENETIC TREE
This chapter provides a statistical assessment of confidence in a phylogenetic tree. The analysis is done with the help of bootstrap procedure. A set of 101 phylogenetic studies was extracted from
On defining a unique phylogenetic tree with homoplastic characters.
TLDR
The present finding allows creating matrices which have as much homoplasy as possible for the most parsimonious or likely tree to be predictable, and examination of these matrices with hill-climbing search algorithms provides additional evidence on the (lack of a) necessary relationship between Homoplasy and the ability of search methods to find optimal trees.
Cladistic Characters and Cladogram Stability
TLDR
For any monophyletic group, Sequential Character Removal generates a list of characters and char- acter combinations that are critical to the resolution of the group, in the context of an otherwise complete data set.
WHY AUTAPOMORPHIES SHOULD BE REMOVED: A REPLY TO YEATES
Goloboff (1991) demonstrated that the ensemble consistency index (CI) is the best measure of the homoplasy associated with the distribution of a set of characters on a cladogram (also see Farris,

Homoplasy Excess Ratios: New Indices for Measuring Levels of Homoplasy in Phylogenetic Systematics and a Critique of the Consistency Index
TLDR
Hers is shown to be more appropriate than CI in comparative taxonomic studies that wish to measure the average level of homoplasy in data sets involving different groups of taxa or different characters, and a new index, the Homoplasy excess ratio (HER), is introduced that takes into account the expected increase in overall homoplASY levels with increasing numbers ofTaxa in systematic studies.
Choosing Among Multiple Equally Parsimonious Cladograms
TLDR
The issue of choice among multiple equally parsimonious cladograms, and three statistics considered, are addressed: the consistency index, F-ratio, D and the D measure, an application of the Shannon entropy statistic from Gatlin (1972).
Simplicity and Informativeness in Systematics and Phylogeny
TLDR
It is shown that attempts to defend phenetic classification have comprised nothing other than abandoning or rendering untestable every claimed advantage of phenetic methods, and there is thus no possible substantive basis for preference for phenetic grouping.
Estimating Phylogenetic Trees from Distance Matrices
TLDR
The distance Wagner procedure is applicable to data matrices of immunological distance, such as that of Sarich (1969a), in which between-OTU comparisons are evaluated but for which no attributes of the OTUs themselves are directly observable.
A randomization test for phylogenetic information in systematic data
-A randomization procedure is proposed to determine if sets of data used for phylogenetic analysis contain phylogenetically nonrandom information. The method compares the observed number of steps on
FREQUENCY DISTRIBUTIONS OF LENGTHS OF POSSIBLE NETWORKS FROM A DATA MATRIX
TLDR
An algorithm has been found for calculation of the expected mean, variance and skewness for random binary data with up to 13 OTUs, based on the number of characters representing each type of partition of the OTUs.
The shape of evolution: systematic tree topology
TLDR
Refinement of Markovian branching hypotheses to include the possibility of multiple furcations, differential speciation and extinction rates for different groups of organisms as well as for a single group through geological time, hybrid speciation, introgression, and lineage fusion will be necessary to produce realistic models of lineage diversification.
A Successive Approximations Approach to Character Weighting
TLDR
Results indicate that the successive weighting procedure can be highly successful, even when cladistically reliable characters are heavily outnumbered by unreliable ones, and computer simulation tests of the technique are described.
The number of evolutionary trees
A simple method of counting the number of possible evolutionary trees is presented. The trees are assumed to be rooted, with labelled tips but unlabelled root and unlabelled interior nodes. The
