曲线一
解释
这里是使用matplotlib来绘制正态分布的曲线。
代码实现
import numpy as np
import matplotlib.pyplot as plt
def test1(n, m=500):
out = []
result = np.random.normal(1, 5, n * m)
print(result)
for i in range(m):
average0 = 0
for j in range(n):
average0 += result[n * i + j]
if j == n - 1:
out.append(average0 / n)
average0 = 0
print(out)
plt.hist(out,bins=25)
plt.title("test (1)")
plt.xlabel("x")
plt.ylabel("rate")
plt.show()
test1(5)
曲线二
解释
这里使用了matplotlib.pyplot来实现指数分布的绘制,具体的代码实现参见下面所示:
代码实现
import numpy as np
import matplotlib.pyplot as plt
def test2(n, m=500):
out0 = []
result0 = np.random.exponential(scale=1, size=n * m)
# print(result0)
for i in range(m):
average000 = 0
for j in range(n):
average000 += result0[n * i + j]
if j == n - 1:
out0.append(average000 / n)
average000 = 0
# print(out0)
plt.hist(out0,bins=25)
plt.show()
test2(5)
曲线三
代码实现
import numpy as np
import matplotlib.pyplot as plt
def test3(n1, m111=500):
out11 = []
# np.random.standard_t
result11 = np.random.standard_t(1, size=n1 * m111)
# print(result)
for i in range(m111):
average0 = 0
for j in range(n):
average0 += result11[n1 * i + j]
if j == n - 1:
out11.append(average0 / n1)
average0 = 0
# print(out11)
plt.hist(out11,bins=20)
plt.title("test (3)")
plt.show()
test3(30)
