How are bootstrap samples generated using the circular block bootstrap (CBB)?

解释:
The CBB uses samples from the original data in blocks of size m. Each block is chosen by selecting the index for the first observation in the block. A total of [] blocks are selected, where n is the sample size where [] selects the smallest integer larger than its input. If the number of observations selected is larger than m due to rounding, only the first n are kept. If a block starts in the last m - 1 observations, the block wraps around to the start of the sample.
