Walking on a tree

  1. 1. Walking on a tree Journal Club – 2014.07.24 Leo Martins
  2. 2. Problem: compare e.g. body mass (X) with speed (Y)
  3. 3. Problem: compare e.g. body mass (X) with speed (Y)
  4. 4. Problem: compare e.g. body mass (X) with speed (Y) Correlation between traits red and yellow is spurious Correlation between traits red and yellow is significant
  5. 5. Solution: for each trait, calculate the constrasts
  6. 6. Solution: for each trait, calculate the constrasts Brownian motion
