更新：

错误可能是由于数据集中还有一个名为“Q”的变量与Q函数冲突。在这种情况下，我如何优雅地解决它？

更新：

您可以下载我的数据集here。

我用statsmodels和pandas数据帧运行一个简单的OLS回归，如下所示：import statsmodels.formula.api as sm

import pandas as pd

df=pd.read_csv("exp.csv")

#df is a dataframe that I have containing many variable names such as AAPL, SPY, INF, etc.

for column in df:

result=sm.ols(formula="SPY"+" ~ "+column, data=df).fit()

但是，df中的一个列名是INF。我猜INF可能是pasty的保留字，代码给出以下错误：

^{pr2}$

我也试过使用Q函数：result=sm.ols(formula="SPY"+" ~ "+"Q('INF')", data=df).fit()

但是，它给出了以下错误：Traceback (most recent call last):
