Question

我正在为Python类的Python Scipy问题挣扎。我试图保持简单明了，所以我可以自己学习。

对此问题的任何帮助将不胜感激。感谢。

Answer 1

如果您特别想使用scipy执行此操作，则可以使用stats模块。这使您可以使用所选参数为分布创建对象，然后可以从中生成从该分布中提取的随机变量。因此，对于dof = 30的学生来说，你可以这样做：

from scipy.stats import t

my_t = t(30)

my_arr = my_t.rvs((100, 2))

Answer 2

np.random.standard_t(30, (100, 2))
