lllcrc model.
lllcrc.boots(boot.list)lllcrc-packagecpi0, gives
the estimated number of missing units at each point; the second, mct,
gives the number of units observed at each point. (Dividing the first
vector by the second gives an estimate rate of missingness)
vgam.crc calls this function for each bootstrap replicate. Many
replicates together can be used for empirical confidence interval
estimation. The bootstrap is much like that described by Zwane 2003, but
more like Method 2 in Norris and Polluck 1996, as we repeat the process of
selecting log-linear terms for each bootstrap iteration, and the multinomial
sampling probabilities are based on raw local estimates instead of
post-log-linear modeling estimates.
