Base function for computing bootstrapped effective size
1 | esize_m_boot(lineup_vec, d, k)
|
lineup_vec |
A vector of lineup choices |
d |
Indices for bootstrap resampling |
k |
A vector indexing number of members in each lineup pair. Must be specified by user (scalar). |
Function to call when bootstrap resampling using boot function (in package 'boot')
If printarg=FALSE, provides only Malpass's priginal calculation of effective size
