当我们需要比较不同组别之间的差异时,森林图是一种常见的可视化方式。通常情况下,森林图展示的是平均值和置信区间(confidence interval),置信区间代表了一个值的不确定性范围。对于基于样本的情况,置信区间通常由样本的标准误差计算得出。因此组别之间的置信区间重合情况,可以反映出差异显著性的程度。 通常情况下,森林图...

What is the formula for finding the natural unemployment rate? Explain the meaning of confidence interval and give an example. Explain why the standard deviation would likely not be a reliable measure of variability for a distribution of data that includes at least one extreme outlier. ...

Formulae used in overridden methods are documented. The infrastructure is documented (e.g. how to create new distributions, How to define new distributions? #12133). The infrastructure natively supports truncated support, wrapped domains, folded distributions, and complex inputs (e.g. ENH: stats....
