我已经毕业了，自学烧OPT中，泪目

今天学习了:

Simpson's paradox:
Simpson's paradox (or Simpson's reversal, Yule–Simpson effect, amalgamation paradox, or reversal paradox), is a phenomenon in probability and statistics, in which a trend appears in several different groups of data but disappears or reverses when these groups are combined.
=================================================================
Bonferroni correction:
Alpha_per analysis < 0.05 --> statistically significant
.1point3acresAlpha_familywise = 1 - (1 - Alpha_per analysis)^{# of analysis}

Correction:
1: Alpha_per analysis / {# of analysis}.
2. Multiply the observed p-value by {# of analysis}.
Both approaches will result in more non-statistically significant analysis.
