statistics bootstrap - Bootstrapping in Matlab - how many original data points are used? -


i have data sets 2 groups, 1 being smaller other. reason, using matlab bootstrapping function estimate performance of smaller group. have code draws on original data, , generates 1000 'new' means. however, not clear how many of original data points used each time. obviously, if original data used, same mean continue generated.

can me out this?

bootstrapping comes sampling replacement. you'll use same number of points original data, of them repeated. there variants of bootstrapping work differently, however. see https://en.wikipedia.org/wiki/bootstrapping_(statistics).
