Data collection was carried out by Etcheverry and al.. The capture occasions represent three consecutive days of trapping in May 1999, July 1999, August 1999, May 2000, July 2000 and August 2000 in the Duchenier conservation area in southeastern Quebec. This data set is analysed in Rivest and Daigle (2004).
This data set's format is the alternative one, i.e. each row represents an observed capture history followed by its frequency.

# According to Rivest and Daigle (2004), a good robust design model # for this data set is formed of an Mth Chao model for each period. # This model can be fitted as follows. ### data(rbvole) ### memory.limit(size=2000) ### rd<-robustd.t(rbvole,dfreq=TRUE,vt=rep(3,6),vm="Mth",vh="Chao") # WARNING : Because the data has 18 capture occasions, the fitting # of this model is very memory consuming; it is long to run!
