ما معنى Family-wise error rate, Bonferroni correction, Holm procedure؟

For $m$ hypotheses of which $m_0$ are true, the family-wise error rate (FWER) of a procedure is the probability that it rejects at least one true null. The Bonferroni correction rejects $H_i$ when $p_i \le \alpha/m$. The Holm procedure orders the $p$-values $p_{(1)} \le \dots \le p_{(m)}$ and rejects $H_{(1)}, \dots, H_{(k)}$, where $k$ is the last index with $p_{(j)} \le \alpha/(m - j + 1)$ for every $j \le k$.
