我安装 statsmodels：
apt-get install python python-dev python-setuptools python-numpy python-scipy
curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
python get-pip.py
pip install pandas
pip install cython
pip install patsy
pip install statsmodels
一切安装完成OK。pip 安装包的位置是/usr/local/lib/python2.7/dist-packages，这样可以吗？因为其他 python 包安装在 /usr/lib/python2.7/dist-packages 中。
当我在 Ipython Qt 控制台中运行此脚本时：
import numpy as np
import statsmodels.api as sm
import matplotlib.pyplot as plt
from statsmodels.stats.outliers_influence import summary_table
x = np.linspace(0, 10, 100);
e = np.random.normal(size=100)
y = 1 + 0.5*x + 2*e
X = sm.add_constant(x)
re = sm.OLS(y, X).fit()
print re.summary()
st, data, ss2 = summary_table(re, alpha=0.05)
fittedvalues = data[:,2]
predict_mean_se = data[:,3]
predict_mean_ci_low, predict_mean_ci_upp = data[:,4:6].T
predict_ci_low, predict_ci_upp = data[:,6:8].T
我收到此错误：
