Okay, guys, new pitch -- if you kill all of us off, then who's going to pay back our student loans? Huh? HUH?

Character set for pictured cladogram (I trust the abbreviations are self-defining)
Code: [Select]
animal         character
           H    MET   RC    P
turtle     0     0     0    0
Horse      1     0     0    0
Wolf       1     1     0    0
Leopard    1     1     1    0
Cat        1     1     1    1


For the next four sets, I literally did a random generator in JMP.  Here's the 1st four sets.

A
Code: [Select]
animal         character
           P    H    P   MET
turtle     0    0    0    0
Horse      0    1    0    0
Wolf       0    1    0    1
Leopard    0    1    0    1
Cat        1    1    1    1

B
Code: [Select]
animal        character
           H    H    H   MET
turtle     0    0    0    0
Horse      1    1    1    0
Wolf       1    1    1    1
Leopard    1    1    1    1
Cat        1    1    1    1

C
Code: [Select]
animal        character
          RC   MET  RC    H
turtle     0    0    0    0
Horse      0    0    0    1
Wolf       0    1    0    1
Leopard    1    1    1    1
Cat        1    1    1    1

D
Code: [Select]
animal        character
          RC   MET   P    P
turtle     0    0    0    0
Horse      0    0    0    0
Wolf       0    1    0    0
Leopard    1    1    0    0
Cat        1    1    1    1



Here's how those four sets would be analyzed, just like any other cladistic analysis, by using only synapomorphies.




And these would be the bootstrap values for our little dataset with a handful of random iterations.

It's all in the head.

General Discussion / Re: SciBabe: Chiropractors are bullshit, yall
Last post by RAFH -
RAFH, that sounds completely airy-fairy nonsense.

Some doctors/people might be better at getting patients to relax, which all by itself might reduce some kinds of pain. I seriously doubt anyone has some innate ability to heal.
Doubt what you like, but in my experience, some people do indeed have an innate way of being, acting, touching, talking, manipulating the joints, muscles and connecting tissue. Perhaps as you say, they relax the patient. Tension in the nerves, muscles and other systems would seem to acerbate pain and make doing anything more difficult. Anxiety certainly does. If a patient is freaked, they will react badly to most any threat they perceive.

On the other hand, I've had doctors and other medical personnel who did just the opposite. They caused tension and anxiety.

Trust is also a big issue and some people exude trustworthiness while others exude exactly the opposite.

I see how that statement can be misinterpreted. I am saying that it shows that some actual dinosaurs are similar to some other actual dinosaurs. We know that it does not show that actual dinosaurs are similar to paraves because of the 65 support value.

This is why I have said that the support indices do not support the dinosaur to bird theory.

Support indices are not calculated in the same way (obviously) as the cladistic analysis calculations.
The high support indices in the early nodes show that some actual dinosaurs are similar to some other actual dinosaurs. We know that support indices do not show that actual dinosaurs are similar to paraves because of the 65 support value.

The problem is that nobody here is very familiar with these support index calculations. Even the authors of the studies are not that familiar as I have found when emailing them questions.
As far as I can see, there is nothing published on the precise questions we are dealing with here.

One thing that seems clear is the following:
Cladistic analysis is based on synapomorphies
Support indices are based on characters. In other words symplesiomorphies are included.


As usual, Socrates is either lying or ignorant about support indices, symplesiomorphies, pretty much every word he writes.

The proportion of trees/replicates in which a clade is recovered is presented as a percentage and referred to variably as the bootstrap value, bootstrap percentage (BP) or, less commonly, bootstrap p-value.





So, with the Xu et al. dataset, 97% of the trees recovered from the standard cladistic analyses (i.e., using shared derived characters, i.e., synapomorphies) had the Coelurosauria node (which includes Paraves).

Last post by ksen -
this ruling specifically limited it to playgrounds, but Gorsuch and Thomas dissented from that part. Gorsuch is going to be even more reactionary than Scalia, who was at least decent on a handful of issues (like 4th amendment iirc)
That part is right.
