pandas.qcut与pandas.cut区别

直接上代码

pd.qcut(factors, 5).value_counts()[-2.578, -0.829]    6(-0.829, -0.36]     6(-0.36, 0.366]      6(0.366, 0.868]      6(0.868, 2.617]      6

pd.cut(factors, 5).value_counts()(-2.583, -1.539]    5(-1.539, -0.5]      5(-0.5, 0.539]       9(0.539, 1.578]      9(1.578, 2.617]      2

==显而易见，cut将根据值本身来选择箱子均匀间隔，qcut是根据这些值的频率来选择箱子的均匀间隔。
