Lab 10: Bootstrap, Jackknife, and Bremer Support

    You may remember finding Bremer support from the lab on “Advanced PAUP,” but I’ll go over it again anyway. First, you’ll need to switch to a new data file—the primates.nex file isn’t a very good example for Bremer support because everything has a really high decay index. 12.

    for morphological data: Bremer support and the Bootstrap. Bremer support is by far the most useful for the amount of data we use as palaeontologists (we rarely have more 100 characters). Bremer support is named after the Swedish botanist Kore Bremer, who devised the method, but it is also known as the “Decay Index”, for reasons that will

    The Decay Index (also known as Bremer Support) (Bremer 1988, 1994; DeBry 2001; Giribet 2003; Morgan 1997) is another measure of clade reliability commonly defined as the number of steps needed to "relax" parsimony until a given branch arrangement collapses in a consensus tree. For the simple artificial data sets in the
