小编Jel*_*ima的帖子

我试图通过使用循环找到最佳参数顺序:

d = 1    
for p in range(3):
    for q in range(3):
        try:
           order = (p, 0, q)
           params = (p, d, q)
           arima_mod = ARIMA(ts.dropna(), order).fit(method = 'css-mle', disp = 0)
                arima_mod_aics[params] = arima_mod.aic
            except:
                pass

我收到了这样的信息:

/usr/local/lib/python2.7/dist-packages/statsmodels-0.6.1-py2.7-linux-x86_64.egg/statsmodels/base/model.py:466: ConvergenceWarning: Maximum Likelihood optimization failed to converge. Check mle_retvals
"Check mle_retvals", ConvergenceWarning)

我想忽略这个警告,我该怎么办？有什么建议吗？

提前致谢.
