To explore the uncertainity in the model fit, this package provides a
bootstrap
function.
The output from running 5000 bootstraps on the full
Moby Dick data set (for a discrete power law)
using the bootstrap
function.
The output from running 5000 bootstraps on the full
Moby Dick data set (for a discrete power law)
using the bootstrap_p
function.
The bootstrap_moby
values correspond to the first row of
table 6.1 in the Clauset et al paper:
bootstrap_moby$gof
the K-S statistic
bootstrap_moby$bootstraps
a data frame for the optimal values from the bootstrapping procedure. Column 1: K-S, Column 2: xmin, Column 3: alpha. So standard deviation of column 2 and 3 is 2.2 and 0.033 (the paper gives 2 and 0.02 respectively).
The bootstrap_p_moby
gives the p-value for the hypothesis
test of whether the data follows a power-law. For this simulation study,
we get a value of 0.43 (the paper gives 0.49).
