Pop Bio Cohort Olympics: 2007 - 2010. (S. Macey)


2010 - 2011 Workshops (Updated 01/13/11)

  • Bodega Phylogenetic Workshop (March 2011)
  • Hierarchical Modeling in Ecology: a practical introduction to understanding and using hierarchical models.  Through two lectures and three hands-on computer labs with ecological data, this workshop will introduce participants to hierarchical models.These models, also known as multilevel or mixed models, allow us to consider more than one level of variability. Multiple levels of variation are nearly always present in ecological studies. Familiar examples include nested study designs or population time series. Traditional statistics can force us to make assumptions about the distribution of variation in our studies. Hierarchical modeling allows ecologists to use scientific expertise to build custom models with the stochasticity that best represents their study systems.

Please note, lab sessions require registration and are currently at capacity.

Lectures and seminar are open to all.
