我正在尝试编写代码来生成一系列arima模型并比较不同的模型.代码如下.
p=0
q=0
d=0
pdq=[]
aic=[]
for p in range(6):
for d in range(2):
for q in range(4):
arima_mod=sm.tsa.ARIMA(df,(p,d,q)).fit(transparams=True)
x=arima_mod.aic
x1= p,d,q
print (x1,x)
aic.append(x)
pdq.append(x1)
keys = pdq
values = aic
d = dict(zip(keys, values))
print (d)
minaic=min(d, key=d.get)
for i in range(3):
p=minaic[0]
d=minaic[1]
q=minaic[2]
print (p,d,q)
'df'是时间序列数据.输出如下,
(0, 0, 0) 1712.55522759
(0, 0, 1) 1693.436483044094
(0, 0, 2) 1695.2226857997066
(0, 0, 3) 1690.9437925956158
(0, 1, 0) 1712.74161799
(0, 1, 1) 1693.0408994539348
(0, 1, 2) 1677.2235087182808
(0, 1, …我试图使用如下代码在python中绘制一组图形.
fig = plt.figure(figsize=(12,8))
ax1 = fig.add_subplot(521)
fig = sm.graphics.tsa.plot_acf(s0, lags=40, ax=ax1)
ax2 = fig.add_subplot(522)
fig = sm.graphics.tsa.plot_pacf(s0, lags=40, ax=ax2)
fig = plt.figure(figsize=(12,8))
ax1 = fig.add_subplot(523)
fig = sm.graphics.tsa.plot_acf(s1, lags=40, ax=ax1)
ax2 = fig.add_subplot(524)
fig = sm.graphics.tsa.plot_pacf(s1, lags=40, ax=ax2)
fig = plt.figure(figsize=(12,8))
ax1 = fig.add_subplot(525)
fig = sm.graphics.tsa.plot_acf(s2, lags=40, ax=ax1)
ax2 = fig.add_subplot(526)
fig = sm.graphics.tsa.plot_pacf(s2, lags=40, ax=ax2)
fig = plt.figure(figsize=(12,8))
ax1 = fig.add_subplot(527)
fig = sm.graphics.tsa.plot_acf(s3, lags=40, ax=ax1)
ax2 = fig.add_subplot(528)
fig = sm.graphics.tsa.plot_pacf(s3, lags=40, ax=ax2)
fig = plt.figure(figsize=(12,8)) …下面的代码应该验证用户名和密码,如果正确应该运行"run.html",否则运行"fail.html",但代码没有按要求执行.代码中的错误是什么？
