Donovan.8: Exercise 8 example data

Description

An example occupancy data set used as exercise 8 in the occupancy website developed by Donovan and Hines.

Details

This is a data set from exercise 8 of Donovan and Hines occupancy web site (http://www.uvm.edu/rsenr/vtcfwru/spreadsheets/?Page=occupancy/occupancy.htm). In MARK, it uses 2 digits to allow a count of 0 to 99 at each site, so the history has 10 digits for 5 visits (occasions).

Examples

# This example is excluded from testing to reduce package check time
# Donovan.8 can be created with
# Donovan.8=convert.inp("Donovan.8.inp")
do.exercise.8=function()
{
  data(Donovan.8)
# Results agree with the values on the website.
  Donovan.8.poisson=mark(Donovan.8,model="OccupRPoisson",invisible=FALSE,threads=2)
# The following model was not in exercise 8. The NegBin model does
# better if it is initialized with the r and lambda from the poisson.
  Donovan.8.negbin=mark(Donovan.8,model="OccupRNegBin",
    initial=Donovan.8.poisson,invisible=FALSE,threads=2)
  return(collect.models())
}
exercise.8=do.exercise.8()
