- c - why is *pp [0] equal to **pp - Stack Overflow
So pp [0] points to the address of p, which is 0x2000, and by dereferencing I would expect to get the contents of address 0x2000 That's were your reasoning strays, but understandably so In C, the right hand side of an assignment, or generally an evaluation of an lvalue (vulgo: variable), more precisely an lvalue-to-rvalue conversion, is already a dereferencing! For example, int i, j=0; i=j

- is there a pragmatic reason to use if (0 == p) - Stack Overflow
It depends on what p represents If p represents a boolean logical value, then (!p) seems most appropriate - comparing to "FALSE" is generally discouraged I don't anticipate this being of much debate If p represents a value, like a counter, then (p == 0) or (0 == p) seems appropriate (There is usually a hot debate between the two I find the first more readable, but the second avoids some
- 统计学中的P值如何计算？ - 知乎
p值：代表的是p值（p-value）是用于衡量统计假设检验中观察到的样本数据与原假设之间的差异程度的一种指标。在假设检验中，p值是指当原假设为真时，观察到的样本数据与原假设相差如此之大或更大的概率。通常情况下，p值小于给定的显著性水平（通常为0 05或0 01）时，我们认为观察到的数据与
- 假设检验中的P值怎样计算呢？ - 知乎
例如，接近 0 05 的 P 值只能提供关于无效假设的微弱证据，而一个相对大的 P 值也不构成支持无效假设的证据，因此，数据分析不应以计算出 P 值而告终，研究者还可以提供其他证据，包括置信区间、预测区间、Bayes 方法、似然比或 Bayes 因子、决策理论模型等。
