python - 属性错误 : module 'statsmodels.formula.api' has no attribute 'OLS'

Question

我正在尝试使用普通最小二乘法进行多元回归。但它说 statsmodels 没有属性“OLS”。公式。接口(interface)库。我正在遵循 Udemy 讲座中的代码代码如下:

import statsmodels.formula.api as sm
X_opt = X[:,[0,1,2,3,4,5]]
#OrdinaryLeastSquares
regressor_OLS = sm.OLS(endog = y, exog = X_opt).fit(

错误如下:

AttributeError                            Traceback (most recent call last)
<ipython-input-19-3bdb0bc861c6> in <module>()
      2 X_opt = X[:,[0,1,2,3,4,5]]
      3 #OrdinaryLeatSquares
----> 4 regressor_OLS = sm.OLS(endog = y, exog = X_opt).fit()

AttributeError: module 'statsmodels.formula.api' has no attribute 'OLS'

Answer 1

为了完整起见，如果 statsmodels.version 为 0.10.0，代码应该如下所示:

import statsmodels.api as sm
X_opt = X[:,[0,1,2,3,4,5]]
#OrdinaryLeastSquares
regressor_OLS = sm.OLS(endog=y, exog=X_opt).fit()
