The following group of tutorials coversthe central notions of descriptive statistics, that is,summarizing and describing the main characteristicsofyour (previously prepared) data:mean, median, variability, skewness, percentil...
统计分析(Statistical)包括描述性统计(Descriptive Statistics)和推断统计(Inferential Statistics)两大部分。面对收集来的数据,我们首先要对数据进行整理(Organization),如排序,统计频数,绘制频数分布表;也可以通过计算一些指标对数据进行总结(Summarization),这些指标包括平均数,中位数等;对已知数据进行整理,归类、简化或绘制...

Additionally, some attributes may not have descriptive names and, in some cases, you’ll find unneeded constructs like using a throwaway variable in the last test. You can manually fix these issues to fulfill your coding style requirements. You already have a readers.py file containing your ...
描述性统计(descriptivestatistics)允许使用定量度量来汇总数据集。例如,数据点的数量是一个简单的描述性统计,而平均值,如均值、中位数或众数是其他流行的例子。数据框架和系列允许通过sum、mean和count等方法方便地访问描述性统计数据。默认情况下,它们返回沿轴axis=0的系列,这意味着可以获得列的统计信息: ...
2. Tests based on descriptive statistics of the sample. Examples are the skewnesstest, the kurtosis test, the D’Agostino–Pearson omnibus test, or the Jarque–Beratest.For example, the Lilliefors test, which is based on the Kolmogorov–Smirnovtest, quantifies a distance between the empirical ...
