Learning goals

  1. Know how to transform a rank frequency diagram to a powerlaw plot.
  2. Understand how powerlaw and pareto plots relate to each other.
  3. Be able to explain why a pareto plot is just and inverted rank frequency diagram
  4. Be able to transform the zipf coefficient to the powerlaw and pareto coefficient and vice versa.
  5. Understand that building the CDF is basically like building the integral.
