Python正态性检验

正态性检验

小样本（<5000):SM检验
大样本：KS检验
from scipy.stats import kstest

1. 首先得到data = [(3000.0, 2),
   (3900.0, 3),
   (4800.0, 3),
   (5700.0, 2),
   (6600.0, 2),
   (7500.0, 4),
   (8400.0, 2),
   (9300.0, 2),
   (10200.0, 0),
   (11100.0, 2)]
   这样的list(zip(data,index))
2. 将data变为series形式
   data_series = pd.Series([d[0] for d in data], index = [d[1] for d in data])
3. kstest(data_series,‘norm’)#表示是正态分布
