NO.PZ2020011101000048 问题如下 How are bootstrsamples generateusing the circulblobootstr(CBB)? The Cuses samples from the originta in blocks of size m. Eablois chosen selecting the inx for the first observation in the block. A totof [nm\frac{n}{m}mn​] blocks are selecte where n is the sample size where [⋅\ct⋅] selects the smallest integer larger thits input. If the number of observations selecteis larger thm e to rounng, only the first n are kept. If a blostarts in the last m - 1 observations, the blowraps arounto the start of the sample. 如题，请具体一下过程，另外这个CBB和讲义里的moving blobootstrap有啥区别？最后提个建议，视频中提到不是重点的地方，习题大多与这些点相关，会有一种感觉就是，不是重点但考的比讲的要深入，分不清是否真的为重要的考点。
